1366 X58 Xeon 5650

Lol, I'd be happy with 4.0ghz!

Will wait and see, hopefully the silicon Gods are smiling down on my xeon lol. Be good to see what it can do, I've not skimped on cooling, got a Noctua d14

Ste · 14 Nov 2017 at 22:18

That’s what I had! 85c under synthetic load for 4.5ghz but mid 50s for gaming. The chips are so cheap they deserve a good thrashing.

Wow that's seriously impressive! What voltage was that at??

The chap I got the motherboard off was running 4.2 on his x5650 with an EK setup on the motherboard but the cpu on air. Not sure what the Asus P6T deluxe v2 Can run these xeons to. Suppose once my cooling bid for the board arrive I'll find out!

Sold the last of my X58 rigs over the weekend. Sad to see it go but had to move to a smaller form factor for the PC I'm using for VR.

Probably up there with the 2500k for the legendary status.

Ignore!

Here you go

My x5670 settings for 4.5 in case any use -

Multiplier 22x
Bclk 205
QPI x36 / Uncore x17
SPD x8
PCIe 100

CPU clock drive 800mV
PCIe clock drive 900mV

LLC level 1
CPU voltage 1.40625v
QPI voltage 1.275v
CPU PLL 1.860v
IOH Core 1.200v
DRAM 1.66v

Everything else auto.

CPU voltage in CPUZ reports at 1.376v

Must admit that CPU voltage is higher than I thought it was

Intel core should be 1.35v, that is intel spec

Ste · 15 Nov 2017 at 15:04

Yeah but screw that when the CPU is worth peanuts

wedrum · 15 Nov 2017 at 15:08

1.4v here

That's awesome, thanks for the info. Can use this as a guide. Will start lower and work myself up to these!

I've removed the EK water blocks from my P6T deluxe now, hopefully my enzotech copper coolers turn up soon. Anyone want nb/sb and vrm EK blocks? Lol

So whilst I'm waiting on my other parts, I've come across people changing the thermal paste on the northbridge on old motherboards. My Asus P6X58D-E would fit in to the "old" category quite easily.

My question is, would it be advisable to change the thermal paste on the northbridge of my motherboard?

Would it make any difference in performance?

I am a newbie when it comes to this, but at the same time I don't want to be running something that could be improved in performance by simply reapplying fresh thermal paste.

Thanks again for your input.

Ste · 17 Nov 2017 at 09:13

Can’t hurt. They used to run quite hot.

KungFuSpaghetti · 17 Nov 2017 at 09:17

Other option if you're concerned about the VRM's and NB getting hot is to spend a small fortune on the Enzotech mosfet and NB copper coolers like I have. Not cheap, especially with postage from the States, but should keep everything cooler!

Saffy · 18 Nov 2017 at 00:35

I think I'll reapply some fresh thermal paste.

Would it be ok to re-use the old VRM thermal pads?

What sort of cards are you guys running with the x5650s? Been using a 7950 and it's fine but for the dual x5650 build I'm doing I have the opportunity to get a 970 for fairly cheap and I'm just curious as to if the age of the chips/pcie 2.0 x16 will bottleneck the card? For the price I'm getting the 970 for it's hard to say no and I'll most likely get it but still curious.

RX 480 with my x5670. No slow down in games on highest settings 1920x1200

I run a 1070 @ 1920x1080, works great with the X5650.

daveyb · 21 Nov 2017 at 12:52

Never managed to get my X5650 to 4.4, glad to know a 1070 is fine with one chip so hopefully the 970 will do well with two chips although considering it'll be 90 quid for a 970 I'm not gonna turn that down.

Is there much difference between the x5650 and a higher chip like the x5670 aside from higher clocks/marginal performance gains?

Stu · 21 Nov 2017 at 15:39

Negligible performance difference comparing PCI 2.0 vs PCI 3.0.

Silicon lottery comparing all the chips in this range. In theory the x5670 is a higher binned chip so there is a better chance of it clocking higher, but experience shows this is generally not the case. The extra multi options may be beneficial, but generally speaking there is little advantage going above the x5660 (from personal observation of many posts, these tend to do a bit better than x5650, possibly just due to the extra multi, and there is very little price difference).

daveyb · 21 Nov 2017 at 15:53

@Stu being that I'll be running two on a Supermicro board there's no chance of clocking it up, was just curious as to if the higher clock speeds would have a noticeable increase, a pair of matched x5650s seems to fluctuate around 40-60 whereas x5670s are 100+.
