Xeon L5639 Overclocking on X58

In 2 weeks I will receive a Sabertooth X58 & X5675...
Curious to see how much oc I'll get from this new-old system vs my P6t Dlx v2@ P6X58D Premium bios + X5650.

Sabertooth+x5675 will be the 'new' main rig and P6T Dlx v2 + x5650 will work as a server and render farm for distributed rendering.
Anxious to see 12 cores/24 threads of this two cpu's @ 4.1 GHz rendering.

I guess it ill be as fast as a new i7 5960x, right?


Maybe I will put the old laptop [i7 620m, 2 cores/4 threads] for the distributed rendering too, for testing and just because.. it will be 14 cores/28 threads.
Damn.

X5675 -- accepting $95 offers..

what clockspeeds can this thing reach? my l5639 is getting 212 bclk for almost 2 years now, i would like a single threaded upgrade for modern games now...

yeah but i want to know the overclocked difference, both are basically unusable stock for games

Depends on the chip you get. You can probably expect about 4.3-4.6 out of a 5670 or 5675 for daily settings given what we've seen across various forums.

 

[Burpo]

Yes, at those speeds, it will be similar (close) to the i7-3770K..

ill probably end up just waiting for skylake then, I was hoping sandy bridge levels of oc, but that's just a silly dream it seems...

 

[dragantoe]

My friend it getting a w3520 as a side-grade from a 8320, are there any motherboards that can overclock well for around $100?

 

[Burpo]

It wasn't that long ago you could get these from Ascendtech for $79 but this one just sold for a bit more..

The intel boards aren't bad, but you have to use their Extreme Tuning software..

ooh that intel looks classy, it seems to have a lot of modern features as well, can he get at least 4.2 ghz out of the cpu on this?

 

[Trinamo]

I'm really working towards finding the right settings for 220bclk on the 5650. I feel like I'm getting really close. I was able to cinebench last night.

The Dell/Alienware ALX board in the top link is what I'm running. Not a lot of OC options like other boards.

From what I can gather with the Cinebench Score versus the cpu-z clock frequency your motherboard can't hold that 23x multiplier under 6 core load and drops to 21x@~4620MHz correct? You may want to try disabling turbo completely then if you are trying to find stability at 220BCLK, it may be the single core jumps up to 5070MHz that are causing issues. If your motherboard does support forcing all core turbo under load though you could enable that but you'd have to drop the BCLK a bit unless you have a cpu that was made with pixie dust and unicorn farts, an all core 5070MHz @ 1.4v would be easily the best Westmere I've ever seen.

 

[Trinamo]

Well the 5650 is supposed to be 22x4 and 23x2 at full turbo. Cinebench doesn't utilize the turbo, never has for me even back when I was just at 190 bclk SO its utilizing only 20x multiplier. Other benchmark programs keep all the cores lit up at the respected full turbo. I checked it while running Firestrike last night. I think the 1.4 is average voltage, I peaking over 1.6 under full load and staying under 70C

 

[Trinamo]

Also the CPU-Z validation wasn't taken during the CB run. When I get home, I'll do that and post.

 

[Burpo]

Cinebench results are accurate, but it reads the default multiplier of the chip & displays as the speed of the cpu.

btw, my CB 15 results are higher than 1011 without ever going more than 211 bclk, so your QPI/memory speed is hurting your score.

What do you mean by QPI/memory speed? Is this something I'm missing and what could I change to improve this? Thanks!

 

[Burpo]

I don't know your board/bios, but Asus has QPI Mode you can set to Slow for higher clocks. I don't use it. Hurts scores.

 

[Trinamo]

I think I have the Cinebench15 thing figured out. You board allows you to lock into the 22x multiplier on you 5650 so that's what CB15 uses on your machine. My Bios will only allow me to lock up to 20x on my 5650 so 21,22,23 is exclusively turbo only on my machine which would cause my CB15 to only go up to 20x and thus give me a lower score even given a higher bclk. Here's a screen shot of HWinfo while running CB on my machine.

 

[Burpo]

Yes, I see what you mean.. That board's not great for overclocking, if it won't let you lock in the higher bins..

Asus P6T Dlx v2 doesn't alow to lock in the higher multipliers in full load on all cores. And it doesn't have voltage offset too.

I flashed P6X58D Premium bios in my P6T Deluxe v2 and now I have voltage offset. But it still doesn't lock in the higher multipliers/bins.
From what I've read if I flash P6T WS Pro in my P6t Dlx v2 I will have the higher bins/multiplier, but without voltage offset. I choose voltage offset instead.

Flashing different bios is dangerous and can brick your motherboard if you don't know what you're doing.
I'm not responsible if you brick your motherboard.

My new Sabertooth arrived today [very fast delivery from UK], I think I'll have voltage offset and the higher bins when using all cores with this board.
The new X5675 was dispatched today from USA so it will take at least one week to be delivered. I wish it's a oc beast.

I'm not using turbo and currently running 200x21 on my overclock and that 21 doesn't change under load on the P6T Dlx v2.

What software are you using to monitor the multiplier as the load is running?

Yes, but your default non turbo top multiplier is 24X correct? It wouldn't drop from 21X, it shouldn't drop under 24X with 6 cores loaded as your top turbo multiplier should be 26X. That is if I'm remembering the chips multipliers correctly, it's easy to get confused years down the road since they have came out.
