Intel 4.5GHz & 5GHz LinX Stable Club

[trn]

I have not dealt with returning CPU's to Tigerdirect but I have returned a 920 to Compusa whom they own. I bought a 920 that took way to much vcore to hardly hit 4.2GHz, brought it back to Compusa and they let me swap it for a new one without asking a single question.

I suspect the retailers don't care because they return them to Intel and probably charge back Intel for the full cost. Intel probably test the chips and sells the working ones to OEM's in batches.

I hadn't thought of that - good idea.
I do wonder what the tigerdirect cpu return policy looks like, I should probably check that out.
I have been doing a fair amount of benching at 1.5 vcore the last couple days - no problems yet.

Here's my first attempt with LinX at 4,7 GHz

[SteveRo]

Nice run mydog!
Looks like linx gflops in broken for you too.

Thanks SteveRo, I'm running on normal watercooling no cold water applied.
Yeah the gflops looks broken here to, did a run without HT and got 94.xx gflops.

Not linx stable but almost as good - pcmark vantage stable at 4.75 but I needed 1.5 vcore to do it. -

Huge score there SteveRo
Can't compete with you there, don't have a storagesystem like you.

I actually returned a 975 to them not to long ago and the staff were all pissed and claiming that the Classified board was my problem, end result: they took it and credited the cc for a full refund.

You got more guts than I taking your 980x pass 1.50v , I can't do it.
Not wanting to bury this chip so soon. jajajaja

Good runs!!!!

[SteveRo]

Good evening, please update my 980x entry.
I wanted to be the first six core over 4.8 linx stable.
I really feel like I'm in un-chartered waters with vcore.
UD7 mobo with ht off -
bios F4, qpi is 36x - 5.76ghz (2880mhz in cpuz)
dominator GT 3x2GB @ 8x - 1280 9-9-9 1T
bios uncore @ 17x 2720mhz
All is well so far!

[SteveRo]

Has anyone topped 100gflops yet?

[Mydog]

Not that I know.
I see that your QPI Link is rather low, what dram and uncore speed are you running?

[Sam_oslo]

OCing the Uncore seams to be a whole new world on these chips.

The RAM and L3 performance is not good on this chip, (at least compared to good old 920), the read/write is down, and latencies is up. The Uncore seams to need a really good OC to follow the core, but (and it is a big butt ) it is not easy to OC the Uncore with this HUGE 12M Cache (which is really slow with high latencies, relatively), without too much VVT.

I don't see anybody pushing the Uncore on these chips yet, but judging based on the locked x20 Uncore on my X5650, these chips may really need a highly OCed Uncore to perform at peak. Anybody has done any tests to share?

good evening,
nothing strenuous on all three.
UD7 -
bios qpi is 36x - 5.76ghz (2880mhz in cpuz)
dominator GT 3x2GB @ 8x - 1280 9-9-9 1T
bios uncore @ 17x 2720mhz
Also - ht off.

first post updated

[zalbard]

All is well so far!

Your temps are excellent so I wouldn't worry about vCore too much just yet.
Great results!

[SteveRo]

Thanks, Zalbard - has anyone broken 100gflops in linx yet? That might be a fun goal.

I can't recall seeing one, wonder why it handles HT so strangely.

I imagine you could get there with that chip, just give it moar uncore mhz and tighten your TRCD and timings a bit

Maybe not 20 pass stable but I usually hit my best Gflops around pass 3 or 4 anyway.

[zalbard]

Nobody with 100GFlops yet, nope.

[SteveRo]

Linx 100gflops -

[Mydog]

Linx 100gflops -

Wow nice SteveRo, what tweaks lead to this?

[SteveRo]

volltages and settings as you see.
Nothin tricky really - qpi @ 36x, uncore @ 24
good cooling and perhaps sufficient nerve to push the vcore where you shouldn't

[Mydog]

Ah I see it now, 30 MHz more and quite high on vcore and you got tough on the timings too.

[SteveRo]

OK so Corsair Labs took the pcmark vantage WR record away from us.

See - http://www.tweaktown.com/news/14682/...le+Feedfetcher

I think I might be able take this back with a 980x oc of only 4.95 (maybe 33x150)
Assuming my cooling can handle it, how much vcore should this take?
Corsair used 1.717v (cpuz) for 5.79 - based on this and my previous posts.
So wadaya think - how much vcore?

[zalbard]

1.6V or so provided it's cold enough.
Do you have a big res? You could buy some DICE and drop it there...

Yep, 1.6 is what I was thinking.
Also yes - I was thinking of DICE also - i would need to go find a pot.

I had a feser quad in the loop for a time - it just heated up the subambient water.

What I'm suggesting is something not requiring a pot, though. No rads, just your chillers (or could do without), pumps and some DICE in a big water res.

[SteveRo]

ok - probably not as cold as a dice pot but should be colder than just the tecs?
What i picture is like a small bucket with dice with tubing running in and out?
