1366 X58 Xeon 5650

That sounds pretty scary! I'm running ap6t deluxe v2

Yep, same motherboard as me. You need to cross-flash to the latest P6T WS Pro BIOS and enable High TDP Turbo Mode to get around this problem. Note that you'll lose some functionality because the boards have minor differences in hardware. The only difference I have noticed is FireWire no longer works (an error is printed during POST but can be ignored and an unknown device appears in Device Manager). I can't guarantee every other feature works since I have only tested what I actually use.

It depends if you could benefit from another 2 cores. The OC on it will be roughly the same as you have now, so in single threaded applications you won't see a difference.

It'll clock higher than 4 GHz most likely but yes it's a minor improvement. Don't forget you get AES instruction sets too though! If you use on-the-fly hard disk encryption this'll make a huge difference.

I know this is a xeon thread, but seems the only place the X58 kit is being discussed now. I'm still running the i7 980 on a Rampage 3 Black Edition board at 4.0ghz with no issues at all. Looked at replacing it but the cost of chip, board and ram is scary.

My concern about the application of thermal paste wasn't an issue when I took off the cooler to replace the X5550 with the X5650.

Had a look at the link and there was mention of there being no offset voltage, quick Google and the P6X58D bios can also be used
Sounds risky flashing it, might buy a spare bios chip.

 

[Saffy]

Regardless it should be better with the X5650.

It is. The X5650 idles at 21C compared to the X5550's 30C. That's a big difference. Although, my "brand new" Cryorig cooler fan has started to make a cricket sound. I've contacted both Cryorig and the retailer. Hopefully, someone can provide a solution.

Yes the P6X58D BIOS can be used but it doesn't provide the option to disable TDP throttling so not very useful IMO. It's of course a bit risky but I did it fine and plenty of others have too.

Nice. My chip idles a bit higher than that but it stays in the low 50s whilst gaming (usually at 4.1 GHz) which I'm happy with.

and it begins, will eventually be dual x5650s. waiting on another heatsink so i can chuck the other e5530 in there and then throw it in a chieftec case. had low expectations it would work at all but when it booted first try i was over the moon.

This is at stock though, so yours is probably better still.

Does the P6X58D Premium not had TDP throttling and offset voltage? Ideally I want both, but if it's one or the other, then the multiplier not throttling down will be more useful.

I'm going to give this a try... I take it that the bootable USB stick I create is for BIOS and not a windows 7 one?

Not sure which of these options to use?
Creating bootable USB drive for drivers or a BIOS update
Setting up BIOS to boot from USB drive

Okay ignore my silly questions, managed to update to the latest WS pro bios and holy crap does that make a difference! 10.89 now on cinebench with x22 multi and 196 BCLK.

Anyone know which x56xx cpu has the highest multi? x24 cpu would be nice to try as temps under load test were 67degrees at 1.4 vcore.

 

[DragonQ]

Ah yes, X58 chips have high minimum clock speeds: 12 is the minimum multiplier so mine only downclocks to 2.26 GHz. Sandy Bridge goes down to 1.6 GHz (same as Nehalem at stock) and 800 MHz has been the minimum for the last few generations of chips.

Does the P6X58D Premium not had TDP throttling and offset voltage? Ideally I want both, but if it's one or the other, then the multiplier not throttling down will be more useful.

According to the thread I linked to, apparently not. I did not try it myself though.

See the "Six Core" section of this table. The X5690 goes up to x27 on all cores but those chips are rare AFAIK. Initially the X5650, X5660, and X5670 were the only affordable ones on the market. The higher grade ones might be floating around now though, not sure.

 

[KungFuSpaghetti]

There's a fair few x5690s on eBay for around £100, but the x5680 is half that! Think that could be the one to go for. 4.4ghz stable @ 1.4 vcore is what I have managed so far on the x5650 and I think that's as much as I'm willing to push it as I'm not really sure about going over 200 BCLK.

 

[Saffy]

I tried 4.2GHz at 1.35v and temps reached low 80C on Prime95 for the duration I ran it.

Then I got a little adventurous and tried 4.4Ghz at 1.36XXXv but it ran too hot at 90+C. I think here's where my cooler maxes out comapred to an AIO. But temps in Project Cars 2 hardly exceeded 60C at 4.4GHz.

So I will have to turn things down somewhat. Hopefully, 4.3GHz is a realistic goal.

Depends what you're doing; if just gaming the temperatures will be manageable compared to Prime 95. However, I do x264 encoding sometimes and that can reach high 80s which is why I don't want to go above 1.35 V.

Haha good to know, I only paid £20 for it. Seem to be limited to x22 multi, running it at 200 BCLK. Would have to bring BCLK up even more to go higher. Is the multi my board or cpu limiting it?

No that’s the limit. I ran 205x22 for 4.5ghz

 

[KungFuSpaghetti]

Thanks Ste, don't really want to push it higher. Stress test one core hit 68, rest around 60. Feel as though that's as far as I'm willing to go on this chip on air cooling.

Wondering if it's worth getting an x5680 with the higher multi, as I'm guessing I could run lower vcore for similar power. Managed 10.98 on cinebench this morning though with a couple of tweaks.

 

[Ste]

There wasn’t much in them other than the higher multipliers being unlocked.

A bclk and a multiplier overclock will result in the same temps.

Those are excellent results on air.

If you paid 20 quid and you’re contemplating getting another one why not give it the beans

Mine was all cores in the 80s under stress testing. 50s in games. Still going strong after two years.

 

[KungFuSpaghetti]

If I could get an x5680 running with a x25 multi on BCLK 196 thats nearly 5ghz
I'd be stoked with a result like that!
Gaming the highest I've seen temps go have been core 5 at 47degrees, rest in the 30s. That's paying pube-g in ultra@1080p.

Have to say I'm impressed with the noctua d14 and fractal design define c case, everything seems nice and cool! Motherboard temps are crazy low too with these vrm and northbridge after market copper coolers.

 

[Ste]

You won’t get that though. There is every chance you’ve got a cracking 5650 and could get a lemon replacement 5680 that won’t do 4.4. They’re fundamentally the same chip.
