Xeon L5639 Overclocking on X58

[Makaveli]

I know the L5640 has a few things against it including a lower TDP and a lower multiplier.

Just wanted to point something out here the lower TDP on the xeon doesn't matter once you start overclocking them. That is only for stock speed these chips will use the same amount of power as the regular six core chips once you get them at the same voltage and clock speeds. So in the context of this thread the lower TDP of the Xeon's doesn't matter since none of you are running them at stock clocks.

My "new" X5650 arrived yesterday and i am able to say this chip is a serious update even from my loved l5639

And is rock stable everything works just fine bench marking and gaming + rendering just WOW

 

[Burpo]

Wow, got an X5660 off ebay, then the guy refunds me & tells me it was a mistake.. wtf? Back to searching..

 

[MongGrel]

What a dick.

Oh well.

 

[goobee]

What a dick.

Oh well.

Fleabay......

 

[Makaveli]

Fleabay......

lol well said!

Was new DL 380 HP Kit with heatsink & 2 fans that I won for $131.62 & I had a $20 coupon. I'm bummed.

Still searching for a deal..

Wow, Burpo your X5650 @ 4.8 gets similar single threaded performance as my stock i5 2500k @ 3.3, judging from your benchmarks. That's actually quite impressive; I thought it would do much worse for single threaded applications.

In fact, I didn't know that overclocking added so much to a processor in general. I wonder how my 2500k would do at 4.5.

 

[Burpo]

I don't use mine for gaming, but crank them up to 200mhz and these Xeon's are hard to beat!
Beats a 3770 in everything but single thread..

Only 1 way to find out on yours

Just downloaded Passmark and tested it, my i5 2500k gets 2125.
The X5650 OC'ed gets a solid score though, considering that it's a 6 core processor.

I bought it 2 months ago for 120euros and it's stable @3800 with multi 20x because my stupid board P6T V2 drops 22>20 because of tdp protection I modded bios with p6t ws pro and multi was OK because you have option to turn of tdp protection but I had another issues like when you boot it says PCI option rom error xxxx:yyyy so I switched again to original bios vcore is 1.25V rock stable with IBT 20 loops prime 24h but can't go higher because temp going over 90C, I have noctua NH12 with 2 120mm cooler master fans @2000rpm but again when i try anything above 3800MHz must raise vcore up to 1.3-1.35V but temps going too high i thought to buy some closed water cooling but the way i see temps will not be much lower if anyone has any advice just shoot


@3800Mhz
Idle temps at room temp 25C are: 28-32C
Under load with LINX or IBT from 82-90C

 

[Burpo]

You're actually good to go. Nothing else you run is going to cause that much load/heat. I run at 4200mhz all cores and experience mid 80's when rendering. 4800 runs too hot and throttles at 95C, so I backed it down. An NH14 is a little better cooler, but your's is working fine. You're not going to see temps that high in anything else you do.

Thanks for letting me know Makaveli. I though that it was locked for some reason, but it makes sense that if it gets OC, the TDP would go higher.

X5650 is the most bang for your $$ because they're so cheap & plentiful. Multi can be set @ 22 instead of 20 and they're $75 delivered (US).

See eBay item number:281361810862

Thanks for pointing it out. I will probably get a couple at that price.

Since they are going for $83/CPU, I am assuming that I should offer $75 per CPU, correct?

TIA!

How easily do the X5650s clock to 4GHz?
Might replace my old 920 D0s at the folks' with some of these.

While not strictly accurate, in multi-threaded stuff it should be roughly equivalent to a 4.85GHz 4770K (figure 4GHz / (1.1 * 1.03 * 1.1) * 6/4)

Edit : Jesus, just glanced at completed listings on eBay. i7 920s are worth almost nothing now (~$40). Man I feel old

Amazing OC's by some of you guys. I'm trying to get my X5660 with Asus Rampage III Extreme to OC above 4.2GHz stable. I'm running 1.35v. The thing runs blistering hot at that voltage. Idles at 45-50C. In comparison, it idles at 26-30C at stock.

What cooler are you using? I think you can get some of the heat down by using adaptive/offset voltage. Also, leaving it at 1.35v may cause issues at higher clock speed. I run mine pretty hard & render @ 4200 (all cores), voltage climbs as high as 1.5 and temps hits mid-high 80's with decent air cooling, but it works

Good scores for an L5639!

X5650 is substantially faster tho. Most bang for the $$ @ $75

In the end, I was able to get 3 X5650 @ $80 each with free shipping. They didn't want to go any lower (I had offered $70 each as my first offer). Since I will be in the US next week, I did get them to agree to ship it to me there so I would get the free shipping. I won't need to pay any duties when flying back to Canada since it will be below the allowance for a 2+ day stay.

I will see which one of the 3 will OC the most and the other two will be replacing a pair of E5520 in an Intel S5520HC Dual cpu board. Even though I won't be able to OC them on the Intel server MB, it should help increase performance and capacity on my home ESXi 5.5 box.

While a few X58 boards were made with SATA 3 chipsets, most of them don't have SATA 3 and those that do don't usually perform much better from what I have read. For some of the better SSDs, that would surely effect performance.

Has anyone played around with an LSI SAS9220-8i in one of these boards. (There are a number of OEM versions of this HBA including the IBM M1015 which you can cross-flash with the LSI firmware with disk pass-through (IT Mode)). It supports 8xSATA 3 channels. Some have been able to push 2000 MB/s locally with 4 SSDs using this controller in their FreeNAS setup.

Since these storage HBA (controllers) can be had for less than $100 a piece (I just got one for my server for ~$80 CND with the 2xSFF-8087 cables), I though one of these might be a great addition to my X58 setup.

I wanted to know if people have had luck in using this board to extend the life of their X58 system along the same lines of adding a Westmere-EP CPU. Most X58 boards have at least a couple of x16 PCIe slots, so it shouldn't be an issue to get all the potential of the HBA.

Hrmm..I noticed it got pretty good storage scores with IRST.
Nothing super-fantabulous though.
More modern boards + AMD still do better.
oh..I have an Areca ARC 1261 2gb..

I received my 3 X5650 CPUs and I am not sure what would be the ideal 24/7 voltages including the CPU and qpi/dram.

I have one X5650 that can boot at 4.5 GHz with a 22X multiplier, but it isn't stable at 1.35v for the CPU and 1.31v for qpi. I can go even higher, 4.7 GHz, and it posts, but it's not stable when it boots (@1.35v for CPU and 1.31v for qpi). It doesn't post at 4.8 with. At that same 1.35v for the CPU and 1.31v for qpi, I can get it stable at 4.2 GHz.

I think I could make it go faster and keep it stable by increasing the voltage past 1.35v, but I am a bit leery of doing that.

I've read at a few spots, including the X58 OC guide where it says the CPU shouldn't be pushed past 1.35v for a 32nm Westmere CPU. I've seen screenshots on this thread where people go past 1.4 V. I've also read in this thread that anything above 1.3v will reduce the lifespan of the CPU.

I've tried another X5650 CPU and I can hit 4.79 GHz at 1.33v and 1.31 for QPI and it's been able to go through memtest+ for over 12 hours without any problems. I was able to boot into linux and keep a load of about 20-30% for a few hours without any issues. I will be doing some other tests on it soon.

I haven't tried my last X5650 CPU yet. I wanted to get some guidance on the "best practice" voltages that I should be using going forward since 2 of the CPUs will be going into my home server (and I don't want to damage them by over-volting them).

As an FYI, I am using a Corsair A70 cooler and the temperatures seem to be under control. For the above setup, it idles at 10° above ambient at 4.4 GHz. The MB is an ASUS P6T6 WS Revolution. I haven't checked the temps yet at 100% load.
