Awesome, Sniper but.............

I think your Gflops is a bit low. Usually on my setup I get low gflops if Vcore is a tad low, or some other process takes up to much cpu time.

[Sniper]

I actually saw 69 gflops last night when trying for 4788, but it stopped with error after the 5 pass.

[newhit]

Have to ask Sniper,
You don't seem too keen on SS. I notice you talk from past experience. What is your dislike of it (I haven't been around for a while)? Also, is this "bclk mod" easy to do (I'm ok with a soldering iron)? What does it involve?
Not to try to get ahead of you of course

I can do 69.xx gflops with the 980x but it has to be with 1GB memory used.
If I go to higher memory the gflps drop to 53.xx at 4GB, odd.
The proc seems to be doing fine otherwise - pcmark vantage numbers are very good.

[Sniper]

The bclk mod is for "old" GB X58 non A mb's wich is limited to max 103 pci bus without the mod.

I'v had 2 SS back in the good old Athlon XP/P4 days, a VapoChill and a Prom. Both worked ok for a while I guess, but there where several disadvanteges for me:
- They produce more nois than my water cooling setups.
- There's allways a risk of condensation.
- Greasy sockets, cpu's and mb's.

The last one is the worst. I like to test out different cpu's and mb's all the time, and with a SS all your parts will be greasy and full of goofy stuff.

You also need to refill and tune a SS to match your cpu's power draw for max performance.

I'm not saying a SS is bad, just not for me and my use.

Ohh, and please do

Just another sleepless night to get me to join this club. My chip needs lot of voltage to get it stable but well, my temps are ok so I guess that's all matter.
Batch #: 3912B168 with HT off and 24C case temp, Watercool as in sig:

Very nice!
Is that with VDroop On or Off?

Without VDroop

[SteveRo]

If I disable hyperthreading on 980x, linx gflops increases from 53.xx to 94.xx -

[Jor3lBR]

If I disable hyperthreading on 980x, linx gflops increases from 53.xx to 94.xx -

That's because Linpack is the only multi-threaded application that actually get worst results with more cores.

That explains also why AMD can turn more Gflops then Intel on the same speeds, but with less efficiency of course.

[zalbard]

Insane, huh?
I think you lose up to 10 GFlops or so with Nehalem... But with Gulftown it's a ton more it seems, lol.

Good evening, I couldn’t resist uping the vcore on this cpu, this is at 1.456v (bios), ht off, cooled via 2xboreas in series, please update my entry, thanks!

Good job it looks like the return of B-batch.

This is a really good results and you don't need to push it more.

[trn]

Then what do we make of the F-batches?

That's really exotic batch#, and I haven't seen any of them in real 24/7 action yet. It is really interesting to see how good they are.
This B-batch seams really promising for now. Have you seen any good F-batch 24/7 results?.

[Sniper]

Nice mhz and gflops SteveRo

[SteveRo]

Thanks Sniper, I wonder how much higher I cuold push vcore w/o doing damage.

[trn]

Your 980x is still under warranty, why don't you tell us

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.

[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 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!!!!

[zalbard]

4.7 @ just 1.44V - very nice! Looks like a great chip!

I just noticed you have my entry at pcie 115, for the 4.7 run I had pcie at auto.
Please update, thanks!

Also - question - how safe is it to continue to bench 32nm at 1.44v?
Is there any real data on 32nm safe bench voltages?

By "bench" I mean usage level of 1-2 hours here and there not 24/7.

Well, imo... 1.45V should be totally safe, 1.5V should be safe also. I wouldn't use more than that 24/7.
For benching just watch your temps I guess... Voltage should be irrelevant.
