overclock

Hello lovely forum, I've acquired a 867mhz with the intention to overclock it. Its battered, but was nice to discover it has 1gb of ram and a working battery. Looking at Everymac, this model was supposed to have a 7455, but looking at motherboard pictures shows 7440 (low power version of the...

I see that most of overclockers here prefer to buy Xeon 3.2 GHz(for FSB = 400GHz) and 400GHz memory. Not a good choice because the entire overclocking process will be limited by memory frequency limit. That is why most of results are in the range 3.4-3.5GHz. I bought two Xeon X5460(3.16)...

hello good day. i have a 2017 15 inch macbook pro here with a radeon pro 555. in windows i can overclock the core to 1000 mhz and the Vram to 1655mhz (can probably go higher but driver limit in windows) i would like to run those clocks in mac-os too if possible. i've heard that core...

There's a lot of discussion on x86 vs Arm already, but in addition to the perf-per-watt war I'm not understanding the value of the Mac Pro vs Studio featuring the same M2 Ultra setup. Where's the value in the Mac Pro unless the clock speeds were pushed higher than the Studio's version? Do...

I've looked everywhere, but I can't find a table describing the position of the resistors for the late 2005 ibooks. I have a 1.33ghz that I'd like to try some frequencies and voltages

Hello all, I recently acquired (for free) a 2010 iMac that wasn't operational. I got the OS running again, but it was all but unusable. So I upgraded the ram from 4 to 8 GB, added in an SSD in addition to the original HDD and ODD, replaced the thermal paste on the GPU and CPU, and upgraded...

Hi all! I am currently trying to build the beefiest Bondi iMac on the planet. At the moment this is the configuration of my Rev B: 512 mb ram / 300 Mhz (overclocked 233 Mhz CPU) Voodoo2 card SSD I think there is still room for improvement. I've read about legends that reballed beefier CPUs...

s anyone know clockgenerator (pll) chip/chips of cMP? It should be on cpu tray. I can't access my 4,1 right now but hi-res photos is ok for investigating. I'm looking for further software overclocking possibilities. Also, looking for ram overclocking possibilities and tightening timing options...

I browsed through some Geekbench scores and stumbled across this: https://browser.geekbench.com/v4/cpu/9270099 A 5K iMac, i5-7600K running with a base clock of 4.4 GHz (instead of 3.8GHz) Single-Core: 5849 Multi-Core: 17959 I'm curious how to achieve this? As far as I know, the i5-7600K does...

Well, after a lot of research and a good bit of info from @LightBulbFun, I finally managed to pull off something I've been working on for quite some time now... Making the world's fastest iMac G4. Back in the day, a company called "DayStar" used to perform such an upgrade for people, installing...

Hello all I have a dual CPU 2009 MP flashed to 5.1 with these 2 main changes -CPUs changed to 2 x Xeon W5690-6 core at 3.4Ghz - total 12 core -GPU changed to GTX 980 TI - 6 gb RAM Did the refurbish myself and all went well for some time until total system crash and collapse, when I gave up...

Retina MacBook PRO 15 2012 w GT650m. When I play games/use high GPU demand soft, my pc start to black screen/reboot, because of GPU reaching 80'+ degrees (or to high clock/voltage). Maxout fans isn’t working. I can underclock GPU in Windows and it fixes problems. Any how to fix GPU in Mac OS...
