Xeon L5639 Overclocking on X58

[Brekyrself]

Whoa.. AscendTech still has the Foxconn Bloodrage Gti LGA1366 Intel X58 for $120 w/free shipping!
Only 3 slots for RAM & no Firewire, but I like it has Legacy support for FDD & IDE.. and it overclocks!

The regular Bloodrage's are fantastic overclocking boards. I have two that can do 220blck without a sweat. They also accept 4gb memory modules which I have ran at 2200mhz stable.

Bloodrage + x56xx + 4gb ballistix for the win.

Well, I think a typo I made has degraded my chip So I'm thinking about making the move to a 5675 and shooting for 5Ghz... what do y'all think? I've benchmarked on this MB 22OBlck with turbo turned off, just didn't like the temps So i wonder if I can do it with a 5675.

 

[Burpo]

You didn't degrade your cpu, but an X5675 @200bclk with everything enabled would be a 5Ghz beast.

 

[Trinamo]

I think it did only because even after passing benchmarks and stress test, I have to keep backing it off every few days because it keeps freezing on bf4.

 

[Burpo]

You think you degraded a CPU because buggy BF4 crashes? Hmmmm..

Here is my Xeon Overclocking experience. I did not do these trials systematically so these numbers are from my memory.

I used Phoronix "Build Linux Kernel" benchmark for comparison. My AMD-1100T based system had a score of 150 and that is my baseline. AMD 8370E scored pretty much the same as 1100T. My i7-4790k machine scored just under 100 for the same test. Score is basically time in seconds hence lower the better.

Edit: All these results with default CPU voltage.

E5620 (4 core 2.4GHz) overclocked to BCLK=170MHz, CPU ran at about 3.2GHz score: 180 and that did not meet my expectation.

i7-930 (4 core 2.8GHz) overclocked to BCLK=180MHz, CPU ran at 3.60GHz score: 140
(While running Intel Burn Test in Windows Vista the system crashed a couple of times and I had to bring multiplier a couple of notches down so the score might be a little lower now).

The performance of an overclocked i7-930 seems to be very similar to 1100T running within specs.

All in all, considering the money I spent, I think it is better to buy a faster CPU/Mobo kit and stick with the default clock unless you already own an overclockable X58 motherboard. It may make sense to extend the life of a setup by overclocking. Overall, purchasing a used X58 board for overclocking purpose will have much diminished returns. My i7 4790k+Motherboard was about $320 from Microcenter. Compare its performance with my used Gene III setup that was $230 from ebay.

That being said, it is certainly a lot of fun!

Originally I was at 206blck with turbo enabled AMD it would pass everything like a champ but crash in bf4. I backed it down to 200 and everything was happy. Then I was attempting to find happy settings back to 204 and made a typo. It didn't take very well. I went back to 200 and that's when I started reading 109W vs 94W and I've been having to back down more and more every few days.

 

[Trinamo]

Its the same type of crash each time. I back the back down a few steps and it runs great for hours for a few days then its back to crashing two minutes in until I back it down again further. I know bf4 is buggy, I don't even know why they released a 64bit version, it doesn't run worth a dang if at all.

You haven't even tried a hexcore? That's where the fun is!

You spent too much on quad core..

 

[Trinamo]

What do you think burpo? Am I just nuts? I admit to being a noon to the OC world

 

[Burpo]

You didn't hurt your chip.. I've been brutal on mine for the past year, testing as high as 1.61 volts, but I bet if I clean the HSF and apply new thermal compound, I can still run 217 bclk max. May do that later today. open test bench gets dusty.

 

[Trinamo]

Ok cool. I'm still learning here. What thing I haven't really messed with because I do not know what it does is the PCIE Frequency. I haven't messed with it at all but my BIOS will allow up to 200. How do I determine a good setting for it or do I leave it at 100?

 

[Burpo]

Yes, 100 is good.. To help stabilize a high overclock, some have had a bit of luck increasing to 102 or 103..

I think my Rampage Gene III is hosed. Now it recognizes only the middle two memory slots :-(
(The reason I bought this mobo was for 6 slots!). Bios or OS won't detect those RAM, but CPU-Z knows how much memory is installed. How can that happen?

 

[Trinamo]

Well this is cool

 

[Burpo]

Well this is cool

lol.. At those speeds & volts, that chip is anything BUT cool

Send it all back for full refund.. Get an X5660 hex-core and a Bloodrage for $200, or get whatever else you want..

Hahaha, One core peaked at 78 and the rest were floating between 70-76. I went back in a messed with a few things, passed IBT max, cinebench and played BF4 for the last few hours without issue. I got it up to 5Ghz long enough to screen shot but I figured I'd be asking for disaster trying to get that stable. It's voltage was peaking 1.6

 

[Trinamo]

Correction: Cinebench and BF4 that was the peak temp. IBT kinda freaked me out, a few hit 90 so I stopped it pronto!

I might have caused that. I tried to increase CPU voltage (very little, I thought!). Memory was working fine earlier, I think. I should have tested memory banks separately, before accepting the board.

 

[Burpo]

It doesn't matter. The board is not performing to spec. Ebay makes it absolutely simple to get your money back now.
Why would you want a quad core anyway when you can have hex core for less?

I just sent a message to the seller. Let's see how it goes.

Edit: Lenovo ThinkStation S20 may not be overclockable, correct?

 

[Burpo]

Unfortunately no OC.. Correct..

Using ebay's money back guarantee system, you simply report it as broken, and they contact seller & do the rest.

 

[MongGrel]

Was just thinking out loud too much, carry on

LOL and that's why I refuse to sell on eBay!

1 yr of dust removed & new thermal compound applied. 217 was no problem
