All We Know About Maximizing CPU Related Performance

[SR2Mac]

Hey HHC:

I saw your BIOS chart (quite the meticulous person are you?) and I was very impressed and very proud of seeing your accomplishment. I can't wait when I'm finally done with my SR-2 Setup and then I'm attacking the same setup that you took from me you to use for my other UD7 build that have. I'm very happy for you !!!!! You have a good spirit about you and as a result you have been able to reap the rewards !!! Good for you, my man !!!

Thanks SR2Mac,

I appreciate that..I am trying. There is just so much to learn. I am glad you can use something from me. I would have kept going but got a snag on the red line. I will continue tomorrow, and keep adding to the chart. Once completed I will sort it, maybe even upload the excel file itself.

Would you have any suggestions or ideas how I could boost my results?
I think my lack of knowledge and understanding has me on a plateau.

Take care,

Hello Tutor,

How are things?
I have been trying out lots of different BIOS settings as per your instructions above...

Attached is a pdf of my results. I was stopped dead in my tracks after the one written in RED. Seems it is the AUTO setting in the uncore setting that killed me. Now the computer will only cycle at C1 then shut off and restart, then shut off...etc.

I suppose I have 1 question:
- Once booted where should I take my testing? Can you see a direction I should go?

Certainly appreciate you helping this amateur sooo much,

- HHC

As an Aside, I just ran GB and CB on my quad core iMac...
GB was: 12,768
CB was: OpenGL 45.53 , CPU 6.83

I probably don't fully understand the number fully, but it sure doesn't seem like my new Macenstein is THAT much better than my older iMac.

I have to figure out how to take it to the next level...

My man, you're hitting scores of near 19,000. That's amazing, so you're already at that "level" !!! How much did you spend (at the time) for your iMac vs your new Macenstein? Also, I wouldn't worry so much about how to boost your results; again, you're doing just fine and it will take time now to tweak your system to reach 20,000+. Even if you can't, remember that even the Dual CPU SR-2 Setup that Tutor has is capping at 40,000 (with 2 x X5680s - the same exact CPU as 1 x W3680).

Tutor's system (because he's more versed in it than both you and I are combined) is hard to compete with right now, because he has spent a great amount of time tweaking. Look at how much time you've spent and your ALREADY near 19,000. Isn't that amazing? Even if you don't get beyond that, hardly ANYONE that I've seen here or on TonyMac has a system close to that speed (with the exception of me at 18,500+ and I'm currently OC'ing). Not for long though, as I want to UC this bad boy. Read how even the new single CPUs are coming along... right about the same speed as yours right now.

Currently your system is about 35% (or 1/3) faster than your iMac. Again, that's amazing, especially for the price difference that you just saved on building this new machine. Those are just my thoughts. BTW, this rendering powerhouse that you have can get even more, if you want a faster SSD read/write speeds (with the money you saved), you can get the new OWC Mercury Accelsior here:

http://eshop.macsales.com/item/OWC/SSDPHW2R240/

In fact I can help you get it and save even more $$$. I know the guys at OWC and want to get one for myself as well. So there you go, you'll have an even faster Mac than you know what to do with. When you're ready and want to go even further in the future, then go with an SR-2 setup for double the speed. But expect to pay double for that.

Be proud of what you've accomplished, I know I am for you... Later...

PS - Remember, a "new" Mac Pro is $9,500 that can reach GBS of 24,000 and your UD7 Setup was around $1,600 (or even less) at a GBS of near 19,000 already. I hope you now see the benefits of what you have and the TREMENDOUS AMOUNT OF MONEY YOU SAVED as a result !!!

That chart you're making is the bomb. Excellent idea! I'd like a copy of it when you finish.

You might profit from beginning to add to step 2 - step 3 at this time. That reset CMOS button can erase your bios settings mistakes. [To bad it won't work to reset everything in life for which we've screwed up the settings - but that's a topic for another time and place.] Judicious voltage tweaks can often come to your rescue, but to use them you need to understand them. Nothing beats self-exploration and you appear to be a master at preserving a record of your explorations. Teach all of us about your system and in the doing you'll become expert in it and an expert in learning how to become an expert of any system to which you direct your focus.

I know I certainly appreciate all your help, that os SR2Mac as well as PunkNugget. Certainly paying it forward. Which I hope to do as well.

Question:
EBIOS read error : device timeout
block 0x620108 sectors 0

This is repeating itself on a screen some 12 times on boot before proceeding...
Any ideas what could be causing this?

Thank you,

- HHC

----------

So would I first copy/past this (from your last instructions):

Then, look for those other words you mentioned to change them after?

Then "bless" it by entering this last?:

sudo su [Enter]
chown -R root:wheel /Volumes/MacintoshHD/System/Library/Extensions/*.kext [Enter]
chmod -R 755 /Volumes/MacintoshHD/System/Library/Extensions/*.kext [Enter]

If I'm incorrect on any of this, please let me know what I need to change, thank you...

I see mentioned several times "bless the system", with the related commands.

Can you explain what it is?
How to do it? Terminal?

Thank you,

As for that error message, you should probably degree pcie frequency a step or two.
As to where and why you bless kext files, you enter the commands in Terminal to set permissions so the file is recognized and then becomes operable; otherwise, you get error messages related to the kext file's inoperability.

SO I took more time today to wrestle with the BIOS Settings. When it all went south I searched google and found this article. http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-bloomfield-and-gulftown/

I found it helpful, mostly for the relationship between settings and definitions. Even though it is an over clocking article it was still helpful.

Here are my latest findings... https://www.dropbox.com/s/jbevtzjvnoizju7/W3680:UD7 BIOS worksheet.xls
I would have loved to have cracked 19000GB and 40 CB but it looks like I will have to settle for now. Feel free to fire any ideas you may have.

I also cannot seem to run the CPU clock higher than 32.

I am currently doing this http://www.mactricksandtips.com/2012/02/stress-test-your-mac-and-cpu.html with 12 terminal windows open. Let's see what happens...right now temps are creeping up to 85C.

EDIT: Attached is a screen shot after the 1 hour stress test.

I also cannot seem to run the CPU clock higher than 32.

That's because of my recommendation that you try to keep the Vcore within Spec VID - here 1.375V to preserve the processor. Also, processors differ in their Vcore requirements and capability to handle higher than Spec amounts. If you elect to exceed the recommended Vcore max for a bench test, you can get to 33 or 34 by adding more Vcore to the dynamic Vcore amount. But exceed Spec VID too far or for too long and you'll start the deterioration of your CPU. Traditional overclockers do it all of the time, but the wisest ones do it only for benches and/or for just a little above Spec VID. Moreover, they have better than average cooling. Exceeding Spec VID is a choice that you'll have to make and live with its consequences. Nevertheless, right now you have one of the highest performing 3680 systems and you have it reined within Spec VID which is better than almost all overclockers can do. Moreover, the average Geekbench 2 64-bit score for a Mac 2010 with your CPU is 15567 [ http://browser.primatelabs.com/mac-benchmarks ]. So your system outperforms the average 2010 6-core Mac Pro with 3680s by a wide margin. Not only that, it also outperforms the average top of the line 2009 8-core Mac Pro with X5570s. Plus you're not overloading it with Vcore and most certainly paid a whole lot less. Those are all quite excellent achievements. And when you arm yourself with more knowledge and apply it, that 18,873 Geekbench 2 score will be a thing of the past.

BTW - your 18,873 Geekbench 2 score and 11.2 Cinebench 11.5 score are comparable to those of my dual quad 5580s.

As for cooling, I recommend the CORSAIR H80 --$105 @ Newegg. Better cooling will improve that score.

Know I understand..I am also choosing to leave the Vcore within spec. I appreciate your recommendation. as far as cooling goes, I am running the H100. One issue with it though. The size of my tower and position of my board leave only room for one fan attached to the rad.

Do you think H100 with one fan is comparable to the H80 with one fan? I have order a thinner fan that should fit on the fit. Noise level though is pretty high so far.

Hi,

Pretty sure this may be reaching slightly outside the scope of the thread, but it must be related as it seems to be BIOS related.

I am still having drive issues. The other day Tutor suggested I degree the pcie frequency a step or two. I tried raising it and lowering it. Still nothing.
My first drive issue is with a cheaper 1TB. It is unplugged now but if it wasn't, on boot I will still get this error repeating many times until it just continues with the boot.
EBIOS read error : device timeout
block 0x620108 sectors 0

Once fully booted the system asks me to initial the disk. Which is weird since it was already done, and I had been using it.

My second drive issue is with my backup ssd. Last night when I went to bed everything was good, even after several re-bootings. This morning though the backup ssd was nowhere to be found. After several re-bootings, and adjusting the pcie frequency still nothing. With the ssd though, the system does even see it, there is no re-initialize option and it can't be seen in disk-utility.

Any miracle fixes?

Thank you,

Lower PCIe frequency to 100 and then repair drive in Disk Utility. Then try raising PCIe frequency just one or two steps. I think the disk got scrambled when you raised PCIe frequency above 103, i.e., 106 and 125, as shown in your chart. 105 is extreme. Don't forget that I pointed out in post # 223 "raising PCI Express Frequency to 102, then next go-round to 103 (this is the max you should try)."

BTW - the cooler you have is fine. I've found that I can get my CPUs cooler by bringing the outside air over the grill and reversing the top front fan to expel: case rear -> fan -> reservoir-grill-> now warmer air -> top front fan->.

I really don't know what I was thinking trying 125

I put it back to 101 the repaired the permissions and then re-booted. Still no second ssd. I placed current BIOS photos in my dropbox:
https://www.dropbox.com/sh/ibny70gscsy25ea/0csjxU0ozv

First, always remember that tweaking implies making fine adjustments after you make yourself knowledgeable about what you are adjusting and with what voltage or frequency. I always assume that the manufacturer got it close to what I want to get from the system. So always notice those default or current values that are revealed on the left hand side of what you can change. They are your breadcrumbs to get you back home out of the forest and they give you an idea of what the manufacturer believed was the best value for the system prior to tweaking it. I wouldn't stray far from there unless I really knew what I'd gain and what I'm placing in jeopardy.

CPU clock drive should be 800mV.
PCI Express Clock Drive should be 900mV.
I wouldn't recommend taking DRAM voltage past 1.67-1.675. At 1.7~, that's waaaaaaay too high, unless the chips are rated that high by the maker. That high is sort of like someone injecting Speed directly into your brain.
I would disable CPU Smart Fan Control. I recommend that the fans run at full tilt. The choice is - mostly quieter now or fully quiet tomorrow because it won't make a peep or a bit loader now and a bit loader years from now because its still running.

Keep in mind that if that high pcie value scrambled a drive, that drive will not magically recover on its own. You've got repairs to make. But it could be that super high DRAM voltage.

Know I understand..I am also choosing to leave the Vcore within spec. I appreciate your recommendation. as far as cooling goes, I am running the H100. One issue with it though. The size of my tower and position of my board leave only room for one fan attached to the rad.

As mentioned before having an H80 in there as opposed to an H100, you're better off with what you have just throw a 12mm scythe fan up underneath that tight area and you'll be just fine. Make sure though it's pushIng cool air INSIDE the unit and not pulling warm air up and out of the rad. But you probably already know that.

If you really want to fully take advantage of the cooling abilities of the H100 then a push/pull config is the best way to go with a fan controller for all 3 fans and leave the scythe fan at its full 1800 rpm. Then bring the other three fans down to a noise level that is manageable to your audible preference. I know you may not like the two fans on top of your system but if you want the lowest temps then this is the best setup.

Actually what I would do is find the best LIGHTED fans and put them on top. Enermax makes a multi-colored fan that is really nice (120 x 25mm) and don't go above 1800 rpm That way others that see it will think that's how you wanted it done to show off the system a bit more. Just a thought...

PS - If you really want keep things hidden, then measure out how thick the H80 is with the 2 x 120 x 25mm fans it comes with and see if you have enough clearance tucking that unit up INSIDE your case. If you do, then that's another option and it will still work near the same as the H100; but just about 1.5 - 2C higher. Not an issue though, since you're UCing...

Well, with UCing I don't think much change will happen but it's cant hurt. I would do it. In fact I did already. I have a 360 & 480 rad with both setup in a push/pull config. It's also all contained hidden INSIDE the case, so I know the feeling you have not having anything attached outside the case. Hope the H80 option will work for you...

In 1987 I purchased a Commodore Amiga 500. Immediately, I swapped the CPU, adding a faster Moto chip, a faster timing chip and a more powerful fan. Did that make it noisier than stock ? Yes. Is it still as noisy? You're damn skippy it is. It's just as noisy now as it was about 25 years ago. I've learned to live with a bit of noise. BTW - That 2k bug was overrated.

I'm still experiencing that same type of persistent noise problem with my 1991 Atari TT030 that I later upgraded to the Moto 68040 CPU and swapped timing chips and added a more powerful fan. These noise problems with my tweaked systems will probably follow me to my grave.

Speking about older pc systems, there was a guy on another post who not only mentioned a clone of one of the older macs, but actually had one that Japan pc makers had called the banana. I couldn't stop laughing when I saw that!!! I'll find the link later to show you the pic. In fact I think Tutor you were also on that post somewhere replying to a comment or two when I saw that pic. Also Tutor, didn't you once work for these companies as a programmer and/or a contributor of sorts? I think it was for Atari as well as Commodore.

It could be that super high DRAM voltage.

Do you think that on my sr-2 setup that the corsair dominator 1600mhz ram voltage that is factory set at 1.65v as opposed to the 1.5v that your corsair xms3 200hz ram is could be affecting things?

WolfPack1 (red), WolfPack2 (black) and WolfPack3 (green) used for graphics and audio - 12 cores x 3 = 36 cores of Visual and Auditory Devastation. I'm in love with my extremely modified Antec Twelve Hundred cases. Each case has 2 - 120mm intake fans toward bottom in front, plus 2 - 120mm exhaust fans in front near the top; one large (200mm) exhaust fan on top of system; 1 - 120mm intake fan on side for PCIe cards and 2 - 120mm rear intake fans near top to cool dual CPUs. The cost of WolfPack3 that scores 34,089 on Geekbench 2 and 19.92 on Cinebench 11.5 = less than cost of 2012 Mac Pro 6-core. In fact, the cost of WolfPack2 (1.12x faster than WolfPack3) and WolfPack3 = cost of 2012 Mac Pro 12-core that each WolfPack performs over 1.3x better than.
