Hey dudes. 1st time poster, looooooong time lurker, very helpful reads from you chaps over the years to keep my x58 humming along.

Got a question for ya'll finally, I'm looking to finally update my i7 920 (still runs strong since 2008) with a x5675 that was offered to me at a very reasonable price locally. The thing is, he's got a bunch to choose from, is there any particular serial numbers that are better than other in this bin?

Searching for this on google yields nothing, but I'm reminded of the days when I was trying to find the best D0 920 I could back in 2008 with the helps of folks over @ overclock.net.

Cheers

Honestly, give it a run and see how far it'll overclock. I got mine to 4.6ghz daily on 1.45v. Maxed it at 4.75ghz but on 1.525v. Those chips are fun to play with.

Hey @Toothless, yours and @lexluthermiester posts make up a lot of what I save, cheers!

Pretty much what I’m thinking at this point, choose one that’s the least scratched. In your opinion there’s no significant silicone lottery similar to the i7 900’s, still got that excel spreadsheet saved from the community project lol.

It a luck of the draw as some are great, some are good, some are ok and, some are dud. As for the serial number I'm not 100% sure if there was a list to go about like in the good old days of 775 socket dual cores and quad cores. You might want to tell the guy that you getting the x5675 but would need to swap a couple of cpus with him in order to find a good all rounder cpu

I've ran a 950 that wouldn't even turbo right when messed with, and a 870 that does confusing things. Every chip is different and you just gotta learn yours. When you do some fun stuff get some benchie numbers!

Ha, wouldn’t that be nice. He’s already doing me a favour opening his forts for business to me under the table during our provincial lockdown :/

Worth asking though, maybe he’ll let me play with a few.

I’m hopeful 4.2 will at least be doable regardless of lottery, but anything north of 3.8 on my current 4core 920 (sucks, I know) would be nice. The 6 core upgrade is welcomed

If you want some chips to play with, let me know. I've got two 920 and one 950 on my shelf that I replaced with x5675's.

Should not be a problem, pending cooling.
Meaning virtually anything but the stock cooler.

Not really. The Xeon's were all top-tier binned A-dies. The B-dies all went to the Core i7 lineup. Like any CPU, silicon lottery will play a factor if you want to OC, but any of the Xeon's will do well.

4ghz should be easily to get to with 4.1 or 4.2 being doable with some more tweaking work.

Welcome to the forums in a non-lurking capacity and let us know if we can be of help!

 

[SeanBeanDiesInTheEnd]

Thanks for the welcome can’t wait to keep this relic ticking some more.

Good to know that about the Xeon, the 920 was great for a good while till degradation happened. At first I thought it was my p6T going, but dropping the voltage and qpi a tad and adjusting the bclk she’s back up to 24/7 @ 3.8 but down from 4.2...

I'm actually amazed the cpu degraded before my version 1 Corsair h60 LOL

If you want some chips to play with, let me know. I've got two 920 and one 950 on my shelf that I replaced with x5675's.

Thank you for the offer, but looking to break the 4 core mold to 6. I actually have a spare 920 c0 I used once upon a time to sacrifice and learn to OC.
One thing I've learned is the C0 (maybe 920 in general) likes:
CPU Ratio Setting: 19 or 21 multipliers
BLCK Frequency: 180 or 200 multipliers

Which led me to this 3.8 setting for my wife's PC on a p6t v1. Keeping it to XMP for stability on some 1.5v classic red ripjaws. Seeing different BIOS settings and have a few resources saved, wondering what new settings await on the x5675

I'm running 18x25 for my x5675 at 1.45v. Pretty sure it'll be fine at 4.2-4.4 on 1.4v. As long as you keep it cool it'll run good. If you do decide on higher voltages make sure to stick a little airflow on the VRMs.

Little asterisk note, I've never been able to overclock with high bclk. Maxing multi and going from there works for me.

I think you said you use a Kraken X60, my H60 currently keeps my 920 @ 62-65 degrees under load so hope it'll still keep things cool with the additional 0.2v increase. Maybe I can thank lapping the hs and ihs a few years back. Aiming to do the same with the x5675 this time around.

The kraken is about 10-15c better than my H70. I'm comfortable with 1.42v with the H70 but past that I'd be a little nervous in a case.

 

[lexluthermiester]

I'm running 18x25 for my x5675 at 1.45v.

1.45v is really pushing it for 24/7 use. Electron migation is a thing and at that voltage the chances of experiencing the same degradation he did before within a year or so is much greater. I personally recommend finding the fastest stable speed you can get to while staying at or under the VID spec of 1.375v.

Pretty sure it'll be fine at 4.2-4.4 on 1.4v.

Probably. But anything above 1.4v is just too risky if long-term use is desired.

Just my 2 cents though..

I know 1.4v is cap for Haswell/Devil's Canyon at 22nm, figured 32nm can handle it a bit better. It's also staying cool but everyone's chip is different.

 

[SeanBeanDiesInTheEnd]

It’s possible there’s headroom gained to push north of 1.4v for 24/7 use safely with the x5675 being 32nm and a tdp of 90w versus 45nm and 130w on the 920. Think it holds water?

 

[Edwired]

Sure Toothless going to fry the chip faster over time with the amount of vcore going through it as lexluthermiester explained it clearly. What the point of pushing it too far as the uncore and qpi link is going out of spec by a mile. Settle at 4.2ghz or 4.4ghz and call it a day. As for cooling I don't trust the AIO coolers one bit don't matter how great they claim it the liquid inside of it going to evaporate along with the pump failing.

As my x5675 is doing 3.9ghz with turbo enabled boost to 4.25ghz @ 1.280v as I dropped the vcore one notch @ 1.28750v in the bios.

 

[lexluthermiester]

Settle at 4.2ghz or 4.4ghz and call it a day.

I would say call it good at 4.0 or 4.1ghz. For an X5675 4ghz is a solid 32% OC, which is damn decent.

Mine Is 38% @ 4.25ghz according to Aida64

Since the system being used to emulate retroarch with pcsx2 core, pcsx2 1.7.0 for testing ps2 games I own, trancoding/converting videos files, multi tabs opened in firefox and not once it bsod since

 

[bobbybluz]

One of my Sabertooth X79/E5 1680 V2 combos is getting transplanted into a new home in the next few days to become my main daily driver. The ASRock Z87 Extreme6/i7 4790K currently in it is is being moved into a well earned semi-retirement. Twice the cores and twice the RAM (64GB) at the same clock speed (4.5GHz) plus a cooling upgrade to an Arctic Liquid Freezer II 280 should be nice.

Only downside is the slightly worse IPC as you're going from Haswell to Ivy. Multicore will make up for it big time though.

Quad channel memory also sweetens the transplant. I consider it an upgrade and worth the effort to do it. A/V file transcoding should be a lot faster plus cooler as well. The 1680 V2's are far better at that than the 4790K but nowhere as good as my X99 2683 V4 and 2699 V4 rigs. I recently swapped the 5960X in my first X99 with the 16c 32t 2683 V4 and there's a huge difference in temps under heavy load, the Xeon destroys the 5960X plus is faster in completing the job. The 2699 V4 is in a class totally by itself compared to all the others.

4.3 @ 1.3v on my 5675's in the SR-2.
Been my daily for a while now. No issues at all.
Running 187 x 23, and yes, the odd multi's OC better.

You using turbo mode?

 

[Mr.Scott]

No.
4.3 all cores, all the time.

 

[Edwired]

No.

Ah I get what your saying my brain had a micro stutter thinking that you did use turbo mode but it dawned on me when I saw the blck you mentioned

Just a question about the cpu/pcie clock skew delay is there any reason it needs to be auto or manually?

Also the benefit of the command rate? Does this boost performance or latency in any way since I checked the ram specs in aida64 it said 2t in the spd information as default. I took the gamble to adjust it in the bios to see does it run at 1t = 1n and it posted but don't see any improvement. Am I missing something here?
