No overclocking?

nah I prefer with CPU ramping up and down when needed, rather than staying at overclocked when idling.

Blasphemy!!

Just fyi, you can still have speedstep enabled while overclocking.

I run my X5650 at 4.4GHz (1.365v), but it idles at 2.4GHz (1.080v)..

I probably will overclock. But I generally do it near end of life of the machine, when the extra speed is worth it. I mean if you're overclocking a 8 core to 5ghz, but only playing WOT it's not worth it. But if you're playing modern games all core are at 95% then overclocking it would be worthwhile, and get framerate boost that prolongs the life of the machine.

These babies were born to clock

also looking at HTPC CPU, from 240e maybe to Athlon II X4 610e or 615e both 45W.

Both Intel & CPU would be from China though

You can do both. Whack multiplier to 20x, set VCore to 1.3 V and set BCLK to 200. It'll ramp between 2.4 and 4.0 GHz unless you turn SpeedStep off.

Heard when OC you should turn SS off.

Shame wouldn't mind selling the 950 and 240e to fund the 6x and 4x chips

koooowweeee · 1 Mar 2017 at 20:21

You only turn it off when you are clocking really high. It can help with stability. 4ghz is easy for these chips

My main system is an X99/5820K @ 4.4GHz but I needed a second system for ESX and a few other bits and pieces. When a mate offered to sell me back my old X58 kit that I sold to him years ago for a bargain price (i7 920, 12GB RAM, Asus P6T Deluxe V2) I decided to go for it. After glancing through this thread I thought I'd pick up a Xeon to see how it goes.

I picked up an X5660 that arrived today so that's 2.8GHz stock. Just had a quick play around with it and it fired straight up at 4GHz (200x20) so I thought I'd go for 4.2GHz (200x21). So far with limited testing it's going well. Has to be said I'm quite impressed with the performance of it, especially considering it's a technically ancient platform. Speedstep is left on so as mentioned above, it now sits at 2.4GHz at idle because I ramped the FSB up to 200MHz and it clocks up to 4.2GHz on load.

Also surprised that having 6x2GB sticks of RAM in it hasn't caused any problems, but it's still early days. Having this kit to play with again has reminded me how much fun overclocking actually used to be.

I was thinking about upgrading to a 5820k about 6 months ago. Would be silly up upgrade to anything with less cores imo.

Would be good if you could post some game benchmarks.

I Have the lowly E5649 6 core its stock at 2.53Ghz and even that i got to 4ghz with all the speed stuff still on. Cooled on a ancient H50 . These Xeons run cooler then our old 900 series cpu's for the same clock imo.
As stated above buy a X5650 or higher and play with it

No need to turn any power saving stuff off unless you're really pushing the chip.

Read that. Especially the 9th post. So true for me. Only just read that thread (well 9 posts of it anyway )

Hey all. I tried running Cinebench to see how my x5650 @4Ghz(ish) compares and it shows only 3.6Ghz. What gives please?

DragonQ · 23 Mar 2017 at 20:55

Ignore it, it doesn't understand the overclock. Windows will show the wrong speed too. CPU-Z is correct.

Any specific reason why you don't just do 20 x 200?

Andy D · 23 Mar 2017 at 23:08

I've tried all sorts of settings, this was only way I found to get it stable. Maybe I just didn't up vcore enough. I can try again with that and see, as I have changed RAM

1.3 volts should be plenty enough for 4Ghz. Whether you do 22 x 180 or 20 x 200 doesn't really matter. Set you multiplier to 16 or 18 first, raise your bclk to 200 and make sure your memory is running at the right speed and voltage. Then set your multiplier to 20 and you should be good to go..

DragonQ · 24 Mar 2017 at 08:42

How high you can get the BCLK depends on the motherboard and other voltages. 200x20 is better because your RAM can run at its rated speed but it shouldn't make too much difference.

I've just picked up a 5670 and am currently stress testing it. I thought it was stable at 4GHz (1.312v on desktop) after passing 8 hours in Real Bench, but it crashed an hour into the x264 stress test. It's currently at 1.328v on desktop and the stress testing is going. I thought they generally managed 4GHz at lower volts. Anyone have any ideas?

My settings are:
Multi: 20x
BCLK: 200
QPI: x36
Uncore: x16
XMP: Disabled
SPD: 8:0 (6x2GB @ 1200Mhz, I'll tweak this later when I find a stable OC)
vcore: 1.31v (1.328v under load, desktop)
LLC: level 2
QPI/VTT: 1.315v
IOH and ICH: 1.2v
CPU PLL: 1.880v
DRAM voltage: 1.64v

Current max core temp 67c, by this evening it'll most likely be 73c.
