Thanks @lexluthermiester and @Zyll Goliath.

Here's a curve ball... I am confused between getting the 1285 v4 and the 1285L v4.

It is my understanding that the one with the "L" is the low TDP version, base clock is slightly slower, and should perform a little worse than the "regular" (non- "L") 1285 v4. However, Passmark rates the "L" version at 401 points higher than the regular non-L.

The L-version is also cheaper, which shouldn't be the case if that benchmark is true.

The "L" version is not listed in the supported CPU list, but it should work. What's the price difference where you live?

Actually, it is listed.

They cost as follows converted to US$:

E3-1285L v4 : $106.91
E3-1285 v4: $134.61

LOL! I looked right over it...

E3-1285L v4 : $106.91
E3-1285 v4: $134.61

The L looks like the better buy, but for that much cost the upgrade really wouldn't be worth it unless you could also sell your CPU and recover some of the cost. If you ended up spending $20 or $30 overall, that would be worth it.

You may also wish to consider the i7-4770 as it would be a better upgrade and is in a similar price range. For example;

Those were my original go-to-cpu plan but they're even more expensive to get. The most sensible reason I can think of is that the 4th Gen Core i7 is relatively more popular due to it being more widely compatible across many 4th/5th Gen motherboards.

The E3-1285 V4 on the other hand, will only work on H97 and Z97 boards.

Anyone have the highest safe voltage for the x5680 chips? No longer limited by cooling..

Here's some of my settings for my x5670

Here's some of my settings for my x5670

I'm running a 1.3875v for core. My issue is the cpu clock stuff. Multi at 23 but there is "speed" which I assume is the bclk? It doesn't exactly say it is.

 

[Edwired]

Mine currently running 4.250ghz, blck 170 @ 1.280v (bios said 1.29375v) qpi/dram 1.24375v

Some board say fsb or bclk is the same thing. Looking at your evga sr-2 it the cpu frequency setting that determining the baseclock

I got it all backwards.

Multi is up and bclk is down. 160x25 for 4ghz. I believe final point is I can't give it more bclk because things start going funky, and same with the multi.

 

[Edwired]

All depends on certain term and condition that would need to be met like you want max multi but only get low bclk or lower multi and get higher bclk as when you start going higher more voltages have to be applied to qpi and vcore mainly. But DO keep an eye on uncore clock and qpi clock as when you go too high on these two that when you get unstable fairly quick

 

[lexluthermiester]

In that second image it shows "Spread Spectrum" on "Auto". Set it to "Disabled". Having enabled or on auto can cause stability problems when overclocking like you are.

That might be your problem. For bclk OCs keeping the bclk a multiple of 33mhz is important to keep the multipliers for the rest of the linked system parts stable, especially for a dual CPU setup. Try 166mhz bclk and see if things stabilize.

So far it's been rock solid with the 160x25, and memory is 1280mhz or something like that, which is fine because triple channel and whatever. Maybe 166x25 will get it to run at 1333 which is what's rated to be at.

Not sure this was meant for me, but "Spread Spectrum" is enabled in my bios, I'm running great at a solid 4.3 GHZ. should I set it to disabled?

 

[Edwired]

Well if the memory is rated for 1333mhz as I'm guessing the uncore should be 2666mhz not above like 3200mhz which might explain the funky issue you were having @Toothless then again I'm just figuring it out by math.

The spread spectrum is used to block out the emi interferences depending on surrounding that might be transmitting like WiFi, router and name a few. I haven't seen much hard evidences based on it been enabled or disabled

When I was overclocking my X5650's, I had a higher BCLK than multi... I believe it was something like 200 on the 'FSB' BCLK and then whatever multi... I'll dig out the Screen shot....

I never really played about with it so much but I don't think I had the best of Xeon's for overclocking, but then I don't think the 48GB of RAM I had in the system helped either... Which is why I swapped it out for 24GB which was again still too high really.. At the time I didn't have 2GB sticks and only 4GB ones which came with the SR-2...

If I ever get around to it again, I'll see if I can get the beast fired up and see if I can figure out a few overclocks It does have in it a pair of X5675's now... I think it's about time we saw if the thing worked still!! lol

 

[Toothless]

So watcha saying is try a lower multi and higher bclk?

 

[Mr.Scott]

Yes. Make sure to use an odd multi also.

 

[Mr Bill]

Here's mine

Yes, it was. In the screenshots you posted I noticed it was on auto. It should be disabled for overclocking.

So watcha saying is try a lower multi and higher bclk?

Yes and....

Yes. Make sure to use an odd multi also.

I've heard this might work also but I've never seen it myself. However, I was very serious about staying close to the multiples of 33mhz on the bclk. 166/167mhz or 200/201mhz are the bclks I have found the most success with. However...

Here's mine

... a non-symmetrical bclk OC is possible. It's just with dual CPU's that clock-sync issues become amplified between system parts.

 

[Mr Bill]

Yes, it was. In the screenshots you posted I noticed it was on auto. It should be disabled for overclocking.

Just went in and disabled it...

I do agree.....to an extent. Every piece of hardware is different. Even identical systems. I have no problem with 166/167 on my system, but it runs my ram a little slower. 200/201 however makes my board really flaky even with the ram on a lesser divider.
On my P6T7 WS SC board, I have no problem well into the 200 range.
So you're probably correct about the dual CPU boards.

Looks like I'll have a GTX1070 in the x5680 rig here soon. Coworker upgraded and forgot what gpu he had. Can't say I've seen a GT1030 with 8 pin power but he verified what he got in old receipts. He just wanted his old desktop running for CNC stuff and I get the 1070 as payment for tech services. Neat.

That's a great deal The 1070's I think are still pretty decent and can fold pretty ok as well What OS do you run on your X5680 rig @Toothless ?

W10 Pro. Usual stuff

 

[phill]

Ah thought it might have had Linux or Windows 7 installed on it

All this showing off of SR-2's, I had mine up and running a few nights ago.. Have you ever noticed that in Windows 7, it would go to sleep, put the CPU/s under load and lock up so you couldn't wake it up???

 

[Edwired]

That would be something in the bios affecting the sleep state for windows 7
