Asus P9X79E-WS + Xeon Processor

Hi guys.

I've been googling for a while to find out whether or not I could overclock a Xeon processor on my motherboard.

Currently I have 4930k installed and I have the system water cooled.



The System is now a little over a year old and I want to improve it a little bit. The graphic card improvement to 980Xs is an option, but I'm not too interested in that option because my system is running just fine with my 3x 290Xs on 4k maxed out.

I ran a stability test just yesterday for these CPU clocks to prove their stability:

That's a little over 1h of Prime95 (still my favorite stress test)

Updating to X99 seems not to worth the effort since I'd have to buy so much new crap and I doubt I'd gain that much. However, my P9X79E-WS motherboard also supports Xeon CPUs, including the E5-2600 v2 gen.

The Intel Xeon E5-2690 v2, 10x 3.00GHz has caught my eye and imagination, but this would only be interesting if I can overclock the CPU a bit. My problem in this case is the CPU strap. On my 4930k I can strap the BaseClock to 125 no problem, and with the multiplier of 36 (turbo) on the Xeon, there are potentially 4.5 GHz to be reached. My 4930k isn't that good of an overclocker and I feel, it is not the best hardware part in my system. With 32 GB memory installed I can't get them to run 2400 MHz which with 16 GB was no problem. Obviously the limitation of the memory controller in the CPU...

The Xeon would easily overpower even the 8-core OC on the X99 chipset. A nice addition for my rending efforts, but a downgrade for my gaming, if the Xeons don't allow a higher CPU strap. Also that would mean I only need to spend 1h on my computer to change CPUs rather than a day, where a full Windows reinstall seems like a good idea.

Does anybody know whether it is possible to change the CPU strap with my motherboard on Xeon processors or is that option entirely deactivated?

It is unfortunately too expensive of an exploration effort I fear, and I rather would look for an alternative to spend my money if the Xeons are not overclockable.

You can only change the BCLK you cant change the multi

Unless you are using heavily threaded programs that will use all the cores and threads you are better off clocking the nuts off what you have.

Saying its pointless buying X99 pretty much answers your xeon question though tbh

Also the 5960X will decimate the E5 2600's - I should know Ive got both! Unless youre talking about the 12 Core which I again have but youre looking at £3000 per CPU and again youd have to be insane for just gaming.

Well the 5960X will with the new motherboard and memory will cost me about the same as the Intel Xeon E5-2690 v2. With the first option I'd gain 2 extra Cores and with the second I'd gain 4 cores compared to what I have. I didn't realize that the 5960X could keep up with two Cores (and 4 threads) less.

I really thought that the Intel Xeon E5-2690 v2 @ 4 GHz would be quite a step faster for rendering applications compared to the 5960X, but you tell me....

Also since you have the dual socket version of my motherboard, I have to ask: Did you try overclocking using the strap function, because, strictly using BCLK I could maybe get 4 or 5 MHz more stability....

I unfortunately cannot push my CPU any further than 4.4 GHz. It's not the best overclocker as I mentioned. Anything beyond that is increasingly unstable...

You still didnt say what Xeon you are thinking about getting but Ive tested 8 and 12 core versions dude. Xeon wise its BCLK only for overclocking and in all honesty - leave it alone!
Youve already got high end kit so upgrading is always going to cost a small fortune - Id honestly sit tight till you dont have to worry about the funds so much. Your games may gain a few extra FPS here and there but nothing worthy of the investment unless you can get a good price for what you have.

How much more precise can I be than to say I'm looking into the Intel Xeon E5-2690 v2? I've mentioned it a few times.

It's that vs. a 5960X...

Does that help?

But if I can't overclock the E5-2690 v2 via strap, it makes no sense. And I really don't want to switch motherboards. Not yet anyway...

If you look at our overKILL3D stuff dude youll see games prefer MHz not cores... The answer to all your questions has pretty much been covered quite a few times in the past.

We even did a Overclocked 6 Core vs Dual 8 Core Xeons....
