Info upgrade to Xeon e5 1660 v3 on X99

[Shmee]

So I replaced my 5930k @ 4.4 GHz in my Asus X99 Deluxe with a Xeon e5 1660 v3 from ebay. It is a nice upgrade with a total of 8 cores now, and it has an unlocked multiplier! This one doesn't seem to be a particularly good overclocker, but I was able to get it to 4.4 GHz currently, at around 1.3V. Currently testing for stability and tweaking. It is cooled by a Noctua D15.

In CPUz bench, it performs on par with a 3700X at this speed in single thread, though in multi thread it is a bit behind.

I currently have the cache running at 3.2 GHz, with 4x4 GB of corsair vengeance at XMP profile of 2666 MHz. Should I push the cache ratio farther? Will this make a difference?

Ok, a bit of a bump here. I want to try tuning the OC a bit. So far I have the chip at 4.3GHz and 3.7GHz cache. But the CPU won't down clock last I remember, and stays at the constant vcore of 1.2 something. I think I need to enable speedstep or something, will have to take a look. Any general tips I can get on this adventure?

Bump! Looks like the comp became a bit unstable as it restarted twice when my friend was playing BF4 on it. Odd that it never had problems in 3dmark or anything else recently. Anyway, I reset to defaults, and will try tweaking again. Not sure if it was the cache OC or the CPU core OC. Any tips anyone could mention? I am thinking of starting by reapplying settings, but backing off the cache clock a bit.

I would honestly not rule out bad programing from Nvidia or EA.
I always ask if the problem is repeatable in either:

1. Program - does it always crash in this program or somewhere in the program.
2. Time - does the problem occur after you sat by the PC for some time. (could be heat / power related)
3. What you see on screen when problem happens - Any artifacting or so on...

But the pc crashing while playing bf4 could mean Geforce drivers are broken or game is broken somehow, especially if it only happens in bf4, before hardware issues.


Anyhow if its not software and hardware.

I would set it at optimal settings then.
Give a slight bump across the cpu voltage settings to see if the chip has degraded from server duty.
Tell your friend to game on it for a week, and bring it back if the problem is repeatable again.

Is this problem only in overclocked settings?

Yeah I was wondering if it was just the game. It didn't crash anymore in BF4 after we reset to defaults, so it may have just been the OC became unstable. Anyway I applied a new OC with the the core frequency down to 4.2GHz, will continue to test.
