my 5675 showed up today.

waiting on some new WC tubing and barb o-rings so I can replace all of them since what i've been using is 7 years old now.

Nice, that should do very well on your board.

Just picked up a ASUS P6T6 WS Revolution for $115. Gotta stop buying stuff.. :D

That is a very nice price for the board.:D

x5675 will overclock to 25 x 173 @ 1.344/1.352 vcore. Highest temperature in Prime95 around 75 degrees Celsius. 22 x 200 requires higher vcore and things get more toasty.

Couldn't pass it up, they also threw in a CPU with it, they didn't mention what it was but hey, it's free and wasn't in the listing. :D

It'll probably be replacing my Deluxe V2 if it all works as expected, more SATA and more PCIe. :) Should give similar overclocking results.

That's not bad. Seems similar to the better x5670's I've had. Do you know what batch it is?
 
You are just really good at making us jealous :)

Honestly if not for eventual need of going NVMe boot drives, I don't think I'll move off of X58 for another 2-3 years

I should have checked the batch but I didn't.:) x5675 works great even at default settings. I played BF4 @ 32 and 64 servers with everything set to High and Ultra @ 1080p 120Hz and it doesn't perform any worse than my i7-3770k @ 4.5Ghz. The usage is approximately the same, give or take 5 percent.
 
What air coolers you guys using for the Xeon's doing 4ghz +? I'm thinking of replacing the ageing i7 930 in the HTPC downstairs with one of these Xeon's but the case is an old Coolermaster Centurion so space is limited for the HSF otherwise I would've dropped my spare D14 in. Will a Hyper 212 or TX plus do the job?
 
I think the Hyper 212x would work pretty good and should match pretty close what im using.
 
These 1366 Xeon's have rekindled my love of overclocking.

Sure the SB 8 cores are a better value, but what fun is it when you can't tweak anything?

I recently built a P6T/x5670 (free board, bent pins) with a Hyper 212 Evo. At 167x24 (4ghz) I think it's just barely enough to keep the thing under control, reaching mid 70's under load and the fan is loud. It was only $20 but I think an extra $10-15 for a Cryorig H7 or Bequiet Pure Rock is worth it for the noise reduction.

A Dark Rock 3, or a bigger Noctua is really needed for a silent 4.4ghz while keeping temps under 80c at load, unless you get a really good chip.

Noctua!
 
I was running a Zalman CPS14X before on my 5670 @ 4.2Ghz but temps were in the mid-high 70s, got a Phanteks TC14 now and we're in the mid-high 60s
 
Swapped my P6T Deluxe V2 with the P6T6 Revolution. So far so good, testing the CPU they threw in with it (I7 965 ES).

I did notice that two fan headers don't work, not a huge issue as I'm not going to use them but I would have thought that they would test that kind of stuff. I have tested everything else on the board and it seems fine.

I noticed that my 840 Evo gives a bit better speeds for whatever reason, about 260mb/s on the Deluxe to 285mb/s on the Revolution.
 
Thanks for the suggestions, I'm currently using the Intel Extreme Edition tower cooler that came with my old i7 980x and it's noisy as hell with mediocre cooling performance. I will have a look at the Phanteks.
 
i'm off to a good start 4.37ghz. only change bclk to 190, CPU to 1.35v and QPI/Dram to 1.33125 (which is what I had with the 920). I also left the ram clock on auto. Not sure if I should select 1600 (or close to it) or not. My ram is 1600 compatible but with the 920 if I changed it, it never worked.

I have HT off and speed step off for now. I will leave HT off though.

what are decent temps for stressing one of these? I'm on water cooling, which doesn't mean my set it is perfect, but I'm seeing 116 to 125 using the CPUID Stress test and CPUID HW

EDIT:
4.37 didn't last long under stress. 5 minutes maybe. I'm at 185 now (4.25ghz)

someone posted recommended safe settings, should I just go with those to start and work backwards onthe BCLK until it is stable? I'll take 4.2ish but man I'd love to see 4.4+

Make up your own mind lol..if you really have the time to start from default voltage and work your way up---go for it!!!! Otherwise i gave you safe values to work down from here

vCore: 1.45v (mine is only at 1.35v but other settings are at listed max safe values)
CPU PLL: 1.9v (try 1.8 to start)
QPI/UCLK/Vtt: 1.35v
vDDR: 1.65v (Possibly QPI+0.5v) (obviously you may have lower voltage ram..and if set set accordingly)
IOH/ICH: 1.25v
PCI-E: 1.51v

I do recommend under clocking the ram vs starting off overclocking it as well......you know set the ram divider as to keep that part separate for now. My ram wont overclock much at all....just saying in case you forgot

LOL, I don't even know wtf the default voltages are!

been going for 40 minutes now a 4.25

I feel so shit being so out of touch with this kind of stuff....I haven't done this since 2009.
 
Brothers:


Strangely the fan headers started working all of a sudden.. :confused:

On another note, this 965 ES has got to be one of the worst clocking 1366 chips I've seen. My w3520 has no problem with 4ghz@1.25v, same with the 920 I had.

Any lower voltage on this and it freezes almost immediately after starting anything intensive.
Hopefully it's not the board, I'll find out over the weekend when I put my x5670 in.

I'm using Cooler Master Hyper 212+ to cool my X5670 @ 4.2GHz. Vcore fluctuates between 1.288 and 1.304 volts and the temps don't go above 65C on the hottest cores while doing some serious video rendering.
 
So what are fairly safe temps for 5675 under load when overclocking?

I upped some voltages today and I'm trying out 4.5ghz, temps are hovering between 49C and 55C

55c under load? That's very good. I'd say anything under 75c is perfectly safe, but I like to keep it under 70c during prime95 smallffts.

i'm using CPUID to stress it...is that not a good program to use? I'm on water as well. Just trying to figure out what is acceptable.

CPU-Z won't stress it as much as Prime 95 or Intel Burn Test. You are on water though, it sounds like you should be able to go pretty far.

I think you'll probably hit the safe vcore limit (1.35-1.4v depending who you're talking to) before the safe temp limit (75c-80c depending how you feel about it :))

Get intel burn test. Should see temps a lot higher. Like 10c or more higher.

Yeah, you're already past what I would be comfortable with, I haven't even went past 1.35v on mine. But if it extra speed seems worth it then why not. :)

Any reason for the PLL bump? I've never needed to adjust it past 1.80v.

i don't know I was looking the safe ranges someone posted. guess I can try dialing it back. I really don't even know what all those damn thing mean anyway or what the default values are.

it isn't stable at 4.5. so I have to bump it back

It should show the default volts on the right side for each setting.

I always set all the volts manually to the "Standard" value, the only voltage settings I've needed to change are the CPU (max 1.35v), QPI (max 1.35v). and DRAM Bus (max 1.65v).
1.4v is probably OK on the vcore, but you never want to go past 1.35v on the QPI as that supposedly can cause much quicker degradation.

QPI is 1.33125v, now my 920 survived on that for 7 years. that doesn't seem to shabby to me. guess i need to keep messing around. I would love a stabel 4.5 but I know 4.25 was solid if I need to go back.

That should be fine, but you may not need that high of VTT unless you are really pushing the BCLK/UCLK. I have mine at 1.2v without issues. Just make sure to stress it or you might get some unexpected crashes. :)

yea already ran into that trying to play armored warfare at 4.5

I dropped it back to 4.37 and dropped the core back a bit and the 1.84v I just put at auto. so far it isn't crashing.

you are right, intel burn test raises temps A LOT. 65C to 72C under burn test.

Add ~10C to that if your cpu support AVX and you have AVX enabled stress test (eg: latest prime95 small ffts.) :D
 
ewll grr.. it isn't survive the intel burn at 4.37 either :(

gaming was fine though at 4.37, wasn't crashing.

back to 4.25

Crash or just too hot? I usually use P95 for longer testing. I use IBT for quick shorter passes.

blue screen, not I don't think it was heat related.

I may just stay at 4.37 unless I start running into issues. I don't do anything that requires super heavy 100% CPU. I pretty much only game

I'm not really sure whether it's really worth sacrificing full stability for a few extra Mhz. What if it crashes when you need it the least. That being said, you guys make me want to push my X5670 over the current 4.2Ghz mark, even though the performance benefit would be slim to non-existant. :D

If it crashes when you need it the least, it shouldn't be a problem. ;)

But yeah, it really isn't worth it unless you make sure it's 100% stable, I could probably push mine a bit more at 1.325v, but the stability risk isn't really worth it.
 
Bigbacon my suggestion is to take a step back and focus on 4.25.....its about what i figure that chips good for in the long run anyways...if you cant pass 10 runs at Max Difficulty on IBT its not stable anyway and to be honest with ya..many of us have passed 10 runs at 4.4 and appear to be good.....but it wouldn't actually last over time. You may run into issues polishing it stable even at that speed......just saying these no shame in 4.25
