1366 X58 Xeon 5650

So any idea on overclocking? I kept my i7 920 at stock for its life (criminal I know!).

Got a rampage II and 6gb of DDR3 1600mhz (with a newly installed 5650).

Any easy guides? Don't need anything major, just curious more than anything.

I'm struggling to get my 5650 stable above 3.5 . I do a cinebench run and I get bsod when temps are only 50 c with core voltage at 1.34 . yet when I leave cpu turbo on I get 4.177 mz on a 1 meg run so I think the chip is good for 4gz just not sure what to do next .

It might be that you are trying to use too many volts, I had a similar issue with a 920 where I assumed I could just keep increasing the volts to gain stability as long as the temperatures were fine, but this turned out not to be the case and dropping my vcore by 0.05V actually let me OC further.

Set the cpu multiplier as low as possible
change the memory multiplier so that when you select 200 blck you will be running at or below 1600mhz memory speed
Then start with about 1.3v QPI voltage then try 200 blck. If it doesn't work then raise it up, ideally 1.35v max.

Once it's stable you can start increasing the multiplier and cpu voltage to raise the clock speed

You don't have to use 200blck but if you can get it stable at 200 it is easier to run your memory at rated speed
 
Hi

TLDR:

i. will these chips work in a Gigabyte X58A-UD3R
ii. performance vs. an i7 920 @ 4.2 and vs. a 4790K @ 4.5-4.7 ish?

I have a Gigabyte X58A-UD3R which if I recall was toward the mid-budget end at the time. i7 920 running at 4.2ghz (Noctua D14) mainly used for iRacing at the moment and for more gaming once I get my graphics cards updated (2x GTX 670 at the moment which doesn't quite cut it at 2560x1440).

Will these Xeon's work in the board? The website says "supports new generation Intel 32nm 6-core processors" which looks positive, can't see a BIOS update post 2012 though!

I was planning to get a 4790K and board deal for c£350 and some new RAM and was assuming 4.7ghz would be doable. This looks like it might be a more cost effective way of getting close to that performance for a lot less though?

I have a xeon 5670 running in my x58a-ud3r (revision 1) @4.4GHz. I think I read that someone else got it working on revision 2 board so it should work on your board.

It is very close in performance when application utilize all the threads, in cases that don't the 4790K will perform better.

http://www.legitreviews.com/intel-core-i7-4790k-devils-canyon-processor-review_143880/14
4790K 4.70GHz score 946 on Cinebench R15 (8 threads)
x5650 4.36GHz score 835 on Cinebench R15 (8 threads)
x5650 4.36GHz score 1006 on Cinebench R15 (12 threads)

Yeah the Xeon definitely needs to be threading properly to get anywhere near the 4790k.

However if you have the board it's a total and utter no brainer IMO. Not quite as worth it if you have to buy a board at the current pricing, mind.
 
It looks like the 5650 would cost around 70 quid and I could sell my 920 for about 35 quid so a fairly cheap upgrade if it all works okay!

My system is currently stable at 200x21 would it just be a case of trying to replicate that or would multiplier issues mean I'd have to achieve a higher stable bclk to get to 4.2?

Assume everyone at 4.4 is on water? :)

on air cooler, don't forget that it is a 32nm chip and also require less voltage to get 4.4 compared to 920.

With bclk 200 you can do the following with the x5650

200x20(4.0GHz) 12 threads full load
200x22(4.4GHz) 6 threads full load
200x23(4.6GHz) 2 threads full load

ideal it is better to have bclk 220x20 to get 4.4GHz all the time.(no turbo nonsense at all)

you should look out for 5660 or 5670 for a better chance of getting above 4.2GHz. I know you can do it with the 5650 but this requires a higher fsb and turbo multis. I prefer to run the fsb at 200 to avoid memory issues etc.

Ideally you will want to be able to run your new cpu at or above the speed of your old i7 so I wouldn't limit myself to a 5650 since the i7 is at a high overclock.

I'm on 4.4 with a h100i aio cooler. its about 15deg cooler than my i7 at full load
