You are using MS 2006 inf. Intel has the correct ones for better/ proper x58 setup. I think that may fix your file transfer problem. If you still can't figure it out, post the name and path of you utility.exe and I will send you a shortcut. If you update and still have slow speeds, I may be able to help you with that too.
I am pretty sure I have the correct INF the one on my disc is the correct one and I did the -OVERALL and it went through the process but there was no change, which makes me think I had the correct version installed but I'm not sure how to tell.. Here is what I did I put the Inf utility in C:/Intel/INF_allOS_9.1.0.1007_PV.exe -OVERALL then double clicked and it ran.. It just immediately said successfully installed..Quote:

Yeah man thanks I have narrowed the problem down to these 1TB Seagate Drives with 32mb cache.. Anytime I try and transfer to these drives from anything else my transfer rates are all f'd up so now I need to know if it's a Seagate problem or a 32mb cache problem.... I would bet on the X58 and the 32MB cache being the problem... Looks like we need one more Inf update somebody call intel and tell them Nvidia called and they want their board back....Quote:

I've raised Vcore even to 1.48 for 4.2 Ghz and still the same thing.
I think I may know what it may be. Tell me what you think.
I am using Gskill 7-7-7-18 1.9V memory.
My memory settings are on auto, but I think it is trying to run 1600 MHz on like 1.6 V, which I think is causing the instability when all 4 core are being stressed.
What do you guys think?
I've ordered some OCZ gold 8-8-8-24 1.65 1600MHz memory which should be arriving next week.
I've run Prime 95 on stock and it works flawlessly, but then again the memory is not clocked to 1600.
So, one way to test this theory would be to lower the Mem ultiplier to 6 and see if I still have that problem?
First is this a typo?Quote:

Also just for info, there was no way to measure the Tcase max (Intel thermal spec) for C2 unless you would modify the IHS and house a thermo couble in the center of the IHS.
So the thermal spec for the C2s was kinda worthless. :yepp:
No, this is the "old" DDR 3 1600MHz memory. I was told that I could still use it on the new system although maybe not to it's fullest extent.Quote:

Well first I have to say that I tried to complete the Prime 95 test but it was not possible due to the high temperatures
That is the reason I keep it 4.2Ghz with 1.35V Hyper-Threading off.
First: Intel recommends it below 1.35, not to care nonetheless.:p:
Second: Load times are 10 to 20c degrees less.
The first screenshot is at 4.2Ghz with 1.37,5 which finished 2 tests as Super PI 1M and 32M.
http://dpweqa.blu.livefilestore.com/...ETh_Uww/20.JPG
The second screenshot is the reason why I can't go ahead with this. I do respect 10%. An example is if the chips runs with a TJMax of 100c then the maximum I would let is 90c. This is far higher than my 10%, check the Realtemp program well. You will see it reached 100c and it was on the 3rd Prime 95 test 1024k which is a bit further than the beginning of the test.
http://dpweqa.blu.livefilestore.com/...IhapRuA/21.JPG
The conclusion is simple and can see by anybody interested on the topic. If you need to use 8 threads with this speed at 4.2 using the best of the best aircolling solutions the Thermalright true copper 2 kilos then It would be better for you to go water cooling solutions as you will get a better voltage than me with 1.38V 8 threads hyper-threading on.
As for me I will stay with my 4.2Ghz at 1.35V 24/7 4 threads no problems. The reason is again very simple, it is cooler with 4 threads, less voltage, programs which I most use can not even use 4 threads let alone 8 threads.
I hope this helps,
No.Quote:

I originally had the same chip as Gligy, but when I went to pick up the rest of the system today they had a fresh order in, so I grabbed one of those instead, as well as upgraded to 6Gb of ram.
The batch number I ended up with was 3839A459, I haven't seen anyone with one yet so I felt brave. Well I'm off to throw the system together. I should have some info later this weekend.
Yeah HT comes with a price, but my goal for 24/7 is ~3.6-3.8ghz with HT on and reasonable temps, ~70-75°C under load with boinc. :yepp:Quote:

I am getting old. I go more for power management and 24/7 operation. I am happy with 30%. And, that was my target. I idle at 31C.
Does anyone have what would be the default volts for the setting (other than CPU and DRAM). I still like to set all my volts manually. If you have that you could save me some time.

Got my i7 920 rig up and running last night, I have some questions.
i7 920
giga x58 ud5 bios F4i
3x2gb patriot 9-9-9, 1.65v
21x196
QPI 3600
mem ratio 8, uncore 16
with cpuz showing 1.45v, multi 20 in bios,
four cores enabled, HT off, I'm priming at 4.1 Ghz, but seems I don't know how turbo mode works. I have Intel's turbo function set to 'on' and giga's enhancement set to 'standard'. At all times, as soon as I'm on desktop, CPUZ reports 21 multi stays at 21 through priming. I thought I was suppose to get the extra +1 multi only when I'm loaded, like when priming. Is there a way that I can get a +1 boost over idle, like when I'm playing a game?
Also, I'm seeing a large difference in my 4 cores temp, 1, 2 are around 63C during prime, 3,4 are 76C. This 13C difference exists all the time, regardless of loading. Is this missreporting, are two cores broken?
So far, seems the only thing that affects my OC is Vcore. Is there any other voltage, like Vtt, that gives me more OC? I have Vtt at 1.36, but I really have no idea what it should be.
Finally, at 4.1 G I'm getting only 10.06 super pi for 1M calc. This seems low a little low in that I think I've seen sub-10 at around 4.0G from others. I believe that perhaps tighter memory timings would help performance for a given CPU clock, I now have my mem set to SPD/auto. What about some of the other ratios? How can I get more performance other than increasing CPU clock?
As promised here are the 4104Mhz stable with "Prime 95".

I will follow you on this one, my goal was 4.0Ghz 8 cores (4 threads for the WCG 24/7) and 4 Threads for the system. The temperatures reach 90c 8 threads priming but I doubt 8 threads will ever be working at full. So at the end 4 threads 24/7 will be at maximum 77c.Quote:

dj883u2, what sort of cooling are you using? Are you on air or water there???

4Ghz 20 Minutes 8 threads =

3.7Ghz 8 threads 7 Hours Prime 95 =

Load minimum and maximum average: 2 hours = 540 / 8 = 67.5
3.8Ghz should be a little higher.
4Ghz to 4.2Ghz means:
200Mhz x 8 cores = 1600Mhz which is converted into heat into heat.
So it looks like is a general problem for aircooling users, this chip is too hot. The only way to get 4.2 Ghz to work with 8 threads is with a good watercooling.
By the way 1 fan 1300RPM 54CFM for me is better than 2 fans as the latter was explained.
This was an interesting week,
Thank you all who participated and contributed to this thread. This is a very good thread explaining many things about this amazing processor.
Well I will keep at 3.717Mhz 1.168V 24/7 8 threads mainly because my goal was to keep 4 to 6 logical processors for the World Community Grid xtremesystems team.
I will only use 4.2Ghz if I need to bench for any reason or if a game does not run at 60 frames per second and the same needs a CPU boost or to play the best Playstation 2 emulator PCSX2 at amazing frame rates which is a CPU eater.
I spent all my money building this system which I do not regret at all however if I only knew the best aircooling solution would not stand for 4.2Ghz then I would have built a water cooling solution. Well there are things we can not go back in the past. It was done and was for good.
I will change to water cooling in the next few months and keep at 4.2 Ghz 8 threads. I still think it is possible to keep such speed with a good water cooling solution. There are good radiators out there in the market.
The CPU-Z Validation: 3.7Ghz 8 threads 1.168

Everybody uses Asus, Intel and Gigabyte Mobos but no DFI LANparty UT X58 why? Maybe too much settings? :D
cause you cant buy the board anywhere right now, etailers here list them avaible @ the 9th.Quote:

If I receive one then i post the results here in the forum !

Thanks. I hope, you will reach good results with the X58. :)Quote:

raise your qpi/vtt a couple bumps as well as pll
Thanks.
Metroid and DJ88 what are your batchnumbers plz?
nilos go back like 4 pages they already posted them
Nice 24-7 for me looks like 3.7- 3.8 is perfect for air 24-7 without stock heat sink. I need better cooling load temps are to high for 24-7 @4g , my load temps were way to high so i did a nice prime at moderate 3.3 27 hrs I dont like seeing it that high of a load temp. Love these new chips:yepp: I especially love the 4 cores 8 threads. Im waiting for the next round of heat sinks :toast:Quote:

On the stock cooler of the 920, I was able to boot up windows and get a cpu-z validated shot of 4GHz. All I did was set the bclock to 211 * 19, the vcore to 1.325v, vpll to 1.9v, and the memory, qpi and uncore multipliers to lowest. Again this is all on stock cooling.
Is that at all impressive or noteworthy compared to others? It was not prime stable, the system froze shortly after starting prime. However I can get 3.8GHz prime stable, haven't tried 3.9ghz. For the third and final time, this is all stock cooling and 2min in the BIOS. Temps have hit 100C with this configuration.
Once DD gets me my new top for my MPC-X38 and D-Tek gets the mounting kit for the Fuzion V2, I will be putting the CPU and chipset under water. About what can I expect with water cooling based on what I've done on stock?
EDIT:
Forgot to mention, turbo mode is disabled for all of this.
Just Got my i7 920 running, here are the results
GA-x58 ud5
920 C0 rev, F4i bios
hyperthreading off
Patriot 999 DDR3, 3x2GB
Tuniq tower 120
Attachment 90352
I sort of cheated in that I benched with HT off, but that is no good for normal everyday use. Reason is Vista sleep mode doesn't work if HT is disabled. Struggling with this reminded me of the bad old days of XP with it's 90 second boot times. With vista, 10 sec is the norm, so HT on is a must.

I got the same Config, except my ram is corsair dominator.Quote:

No luck for me using R2E with a Core i7 940. I already tried two CPUs and the highest rock solid stable I can get is 3.8GHz (19x200MHz) with 1.28V in BIOS, QPI/DRAM voltage is at 1.43750 in BIOS. Ram is Corsair Dominator 1600 @ 1600MHz with 7-8-7-22 timings at 1.65V in BIOS. Air cooling with CoolerMaster V8.
I do not know how everyone is managing 4GHz OCs even with 920 when I cannot even get any of the 940s to 4GHz. Maybe it's my cooling? Temps are maxing out at 77C (ambient is about 22C).
This is starting to suck badly...why pay for a 940 when it works no better than any 920 out there...
Any others users with R2E and a 920/940 on air to give some tips on breaking that damned 4GHz mark? These chips are supposed to be higher binned than 920s but maybe w/out WC or something better they cannot fully stretch their legs?
Any tips appreciated!

Save that link. It hasn't changed for months.
It's winter time here so there has been lots of time for updates recently. :)
maybe scroll down some posts. :rofl:Quote:

higher vcore brah :cool: 77c is nothing with these. 1.28 just isnt enough unless you have 1 of the 2 cherry i920 floating around here. Loosen the ram up for now too 9-8-8-24Quote:

Thanks but i downloaded it yesterday.Quote:

I hope this info will help you guys out on the quest of getting a very good lower voltage with higher clocks.
Aww come on, no input on this?:rolleyes: Please humor me or at least give some pointers... I'm really just trying to keep myself occupied until I can get the darn thing under water! :up:Quote:

I will come back to report.:D
No pics, I'm using the gravity method right now. That is, I set my case down flat on it's side and the HS is just sitting on the top of the 920 with some light bracing. Tomorrow, I'm going to make a proper hold down by screwing down a piece of sheet metal to each end of stock 'H' hold down to effectively enlage it so that it extends beyond the mobo holes. With holes drilled in the sheetmetal aligned to the holes in the mobo, I'll run the stock screws down into a custom backplate. This will allow me to turn the case up onto it's normal upright position...at least in theory.Quote:

Looking for more now!
Are you on air or water?Quote:

The maximum I could get stable with 3.7Ghz 8 threads at 1.14V. You still have a difference of 3 to 5 volts which has a better yield than my chip :D
