99belle99 BCLK: 200
Multi x 21

Turbo off, All other power saving on.

Vcore 1.3 V

QPI/Vtt: 1.235V everything else auto

It's a while since I messed with my X58 so this all from memory but I was running my X5660 at 4.2GHz for a few years and could push to 4.6GHz and 4.8GHz for benchmarks. But 4.2GHz is best all rounder not putting too much strain on system.

Another thing QPI is 7200 and RAM multipier set it so RAM is 1600MHz.

paiNsage Hey Kana,i wanted to ask you if you could explain a bit of your thinking process when overclocking,i guess i want to ask you how to overclock my x5660 chip.. Seeing that the website on the first page is down,the only way was through a message... These are my specs:
X5660
P6T SE motherboard
3x4 (12gb) Micron ddr3 1600mhz memory
650w Cooler master MWE Bronze PSU
Snowman cooler with 6 heat pipes (Still waiting for it to arrive )
I've asked a few people on the forums,and they said that you were the god of X58 Xeon overclocking,so i wanted to learn from the best (if possible )
Im basically a newbie on x58,never had it,so this is the first time.. If you could explain a bit of your overclocking methods,that would be great..
Thanks for your time and effort .

Kana-Maru Prime95 still has it's purpose, but be careful with it as with all stress testing. I guess you won't really know how stable a machine unless you stress it for many hours under different conditions. I usually make sure I'm rock solid by stress testing for MANY hours or a few days at a time when I can monitor the machine.

Many years and counting and I've never had a crash @ 4.6Ghz or 4.8Ghz + 1600Mhz RAM or 2000\2100Mhz ECC Server RAM. I Since this machine is so old now I run it at 3.8Ghz most of the time and can still get great FPS @ 4K with 2019 games WHILE recording. Can't wait for RDR2 to release on PC.

HDDs are simply affordable, but there are good 1TB SSDs with great speeds around $90-$110 dollars now. That still doesn’t compare to 1TB to 2TBs HDDs for only $40-$55. The speed makes up for the SSD price though .



SSDs also seems to have better reliability since I’ve been running my 3 SSDs (2 of them in RAID) for several years now. I had a bad experience with a SSD back in 2013. Took awhile to get over that fear lol. I’ve been looking at PCIe M.2 cards and RAID cards.









No problem. You can use quite a few programs. Prime95 is a good one for RAM\CPU and many other components, but be careful not to damage anything from the heat. IntelBurnTest is old and nice + it can really cook the CPU. MemTest64 for RAM. For GPUs you can use Furmark or the presets. Cinebench R10, R11, R15 and R20 are good test to see how stable your build is. There are many others as well, but that should be enough to get your started.


Still the “good ol prime95” then heh. I’ve been using it myself since I started OC’ing when I got a 2500K many years ago.
About a year ago I was able to get a leftover PC with X58 motherboard. At that time it had the i7-920 that I switched out to x5670.
From the sandy bridge days I’m used to using prime for testing as well. After the shorter initial tests I run custom test with full FFT range, 90-95% memory and 10 minutes for each test. If that doesn’t crash for 1-2 days then I claim it as stable.
Do you think that IBT would do the same or better job quicker or long prime test is still the way to go?

Features such fan controllers and expansion slots such as 4 HDD slots + 2 HDD slots for RAID 10 and RAID 1 setup. I guess I could switch to all SSDs to replace my HDDs, but the HDDs (2TBs+) prices are so much more reasonable.

Plus I have a fan controller (5.25mm) then there's the issue of air flow. The older X58 NEEDS great air flow which appears to be lacking in a lot of nice looking cases. The AIOs also don't seem that great since older hotter units aren't the target. I wish I could find my older Kuhler CPU cooler, but they no longer make them, but my current AIO for now.

Then again I guess I could use that money I would spend on a nice case to get more performance upgrades or something. I don't know. I never know since I'm still enjoying this platform and plan on getting as much performance out of it before I build a new PC.

99belle99 It needs more voltage though for 4.807GHz for some reason. I can get 4.784GHz at that low voltage but for those extra Hz the voltage goes up. Still a pretty good chip.

1.42v isn't going to degrade the chip in any way shape or form, or not in less than 2 years anyways, I degraded my X5670 pushing 1.52v, around 1.42v you're not going to have any issues, but either way the higher skews up to the X5675 tend to be better binned in my finding, my X5660 will do 4.2GHz with 1.32v but for even 4.5GHz it needs 1.45v and for 4.6GHz it needs 1.5v but that seems to be an average bin for an X5660 so you definitely have a unicorn level bin there if it does 4.7 at 1.42v
