1366 X58 Xeon 5650

So I was thinking, since the X58 platform has the memory controller in the CPU itself would that mean that ECC memory could be used?

I have a gen 1 gigabyte ud5 (oldest version) and a x5660, is it possible that ECC would actually work? if so it would be great as its cheap as chips on the bay.

Anyone had experience with this?

I believe the Xeons do support ECC memory yeah.

Yep they do but I wonder if the motherboard has to support the memory also, I cant find much info about it other than the odd failure/success story with similar boards.

Only a single post so not definitive but this user couldn't get it working. Board reported a C1 memory error

It seems buffered ECC is a 100% no go on these boards but it seems a few people have gotten ECC non buffered to work which is no where near as cheap it seems

put my x5650 on the bay place, no interest at all. must be worthless now

You would be surprised, I think people still buy these chips. Problem is with auction sites you don't always have the right person looking and a lot of the time people will just want to buy it and for it to ship straight away rather than bid and wait.

Although saying that the X58 platform is getting on a bit now, there is only so many motherboards around that can take advantage of these chips.

You'd have better luck selling if you put it on the Members Market here but you'll need to post a bit more as I believe you need 1000 posts before you can use it. :cool:

yep, and when I get to 990 posts it will jump to 10,000 posts

well you can get 8 core sandy chips for ~£60 so they aren't worth as much.

Uncle_Gravy · 15 Apr 2016 at 09:14

As above, quite a few X5675s are below the £100 now.

They dont fit in a 1366 board though

Probably already been answered but GL finding it in 77 pages.

Max safe voltage for the 5660?

Cheers.

Ste · 16 Apr 2016 at 09:15

I believe Intel spec sheet says 1.35v

I've been at 1.375v (1.41v bios) for about a year now

tribz · 16 Apr 2016 at 09:28

Thats pretty much what I used also, 1.375 and worked my overclock around that.

pioneer2000 · 16 Apr 2016 at 12:04

Does everybody go by bios voltage or Windows?

Surely the safe voltage is 1.4V per BIOS?

I'm currently at 4.2Ghz (1.39375 vcore in bios, 1.36v in OCCT.

QPI is at 1.315v BIOS, which seems high to me but I cannot seem to get stable any lower.

CPU PLL is 1.8v (doesn't seem to make a difference to anything).

Strictly speaking you should stay within the Intel Specs which clearly state 1.35v as the upper voltage. CPU-Z gives a more accurate voltage reading than the bios settings, only bettered by a Multimeter.

Personally I generally go 0.05v above the Intel Specs (so 1.4v) and have never had any problems in all the years I've been overclocking. You just have to make sure you have good cooling and keep the load temps down. I'm running the X5670 I kindly got from Tribz at 4.6Ghz with 1.4v in CPU-Z. Cooler is a Noctua D14 and load temps just about touch 70c

pioneer2000 · 16 Apr 2016 at 14:59

Oh, just read something that has completely changed my outlook on this!

http://www.overclock-and-game.com/hardware/computer-tech-news/30-westmere-ep-x58-overclock-information?showall=1

So appears 1.35v is the max recommended vcore BEFORE the potential +0.05 voltage spike.

Hmm, what's the thought on LLC? Enabled or disabled?

Uncle_Gravy · 16 Apr 2016 at 18:54

That's good then, 1.235v is safe then

Just wanted to make sure what my limits are.

Wow, what are you using to put it under load? I have the same cooler but my load temps are closer to 85.

Ste · 17 Apr 2016 at 08:55

The BIOS voltage is meaningless as its all in theory and will vary by the condition of the board, power supply, etc. Go with CPUZ.
