TPU's Core i7 Overclocking and Feedback

[SystemViper]

I Don't think there is too many people that is an overclocker that can say, I never RMA's anything that I knew i blew.....

 

[Fitseries3]

dispite what you guys think of me i have only RMAed 2 things ever in my life. one i didnt even EVER use... it was given to me dead.

1. diamond 3870
2. i7 920

the i7 was killed by my p6t6 when the vrms shit the bed. NOTHING i did to it.

This is true. We've all done this one or twice. I just tend not to do it anymore.

I believe you, and I don't think anyone would hold it against you.

Could we start posting our 24/7 clocks and vcore? I think it might be helpful. I'm running 4.1ghz on 1.4v....

what list is that?

here are my stable everyday settings.

lol

posted over there, thanks binge.

This is off-topic, but I have my pc folding at 3.8GHz 24/7 with the SMP client, it only supports 4 threads, but it products 3.3k ppd, and I still can play game without any slowing down (Dawn of War II, FEAR2, and the Empire Total War demo), so if you can, I think you should start folding... for Techpowerup, you won't notice any slow down AT ALL.

damnit i tried 1.33vcore, 1.4vtt, uncore, vdimm (tried 1.6vdimm as well) and ram timings on auto and it still won't post at 173bclk. i dropped the multi down to 12x and it doesn't post either. batch is 3838a and according to google its a pretty bad batch. any way i can rma the chip?

As you mentioned in the Batch thread we have the same batch of chips... Might be that I ran into a crap OC chip too...
I'm dubbing on whether I want to exchange this chip or just keep it at 3,66... Though I can post 4Ghz, it's just hella unstable and I need major voltage to do so.

Went playing around again tuesday night and I am trying to see a pattern in vCore versus QPI/Vtt voltage. I could boot into 4 Ghz with vCore ranging from 1.4 to 1.5 volts, with results ranging from reboots before Windows to BSOD's the second I start a stresstest.

I did notice that with a lower end vCore, a lower QPI/Vtt got me further on the boot. I ranged QPI/Vtt from 1.200 to 1.360. The "ideal" settings are yet to be found as I still can't do a good stress test.

 

[Fitseries3]

qpi/vtt needs to be around 1.4v to be stable at 4ghz

 

[Thrackan]

qpi/vtt needs to be around 1.4v to be stable at 4ghz

I have a hunch I need to check on tonight. It involves what you might call "harmony" between the vCore and QPI/Vtt and how to get it.

 

[Fitseries3]

you are on to something yes.

1._ <- the blank is usually filled with the numeric value of the OC.

4ghz = 1.4v vtt
4.2ghz = 1.42v vtt
4.5ghz = 1.45v vtt

thats my findings.

and yes i tested 4.2ghz at 1.4v and i get bsod or hardlock after about 10mins.

So I got a really great e-mail back from DFI,

Bill,
Have only seen two complaints of some odd noise on the LP UT X58-T3eH8 motherboard. The customer in question here has already rma'd his board to the seller for a refund. However hearing acuity may vary from person to person. As I have aged I have lost some hearing, but still can hear 3 of my video cards that make a high-pitched noise when loaded heavily. That said, I have heard no sounds emanating from my UT X58 board. No reports of any noise coming from any of my three "close" friends running that board overclocked and one with all 6 memory slots with memory installed.

The problem is that some sounds maybe totally un-detected by one user because of their level of hearing and then another user may hear something odd and there is no way to know when this might occur. As said have only heard of two users with some odd noise issue on the UT X58 board out of the many already sold, so that seems to indicate that an odd noise from the UT X58 boards is not a normal expectation overall.

Intel rates the current crop of i7 processors at 135 watts under load which is 107 amps with Vcore set to about 1.26 volts. So even if an over-clocked i7 processor were to somehow draw twice that 107 amps the board PWM circuit would still have headroom of 150 amps. I would think a cpu that had twice the rated current capacity drawn thru it would not last long. I would think the cpu might actually fail before the board's PWM circuit would fail, even at twice the current thru the cpu than Intel's rated amperage/wattage when running at 1.26 Vcore.

So Bill, when I am faced with this sort of situation, it is very hard to determine exactly what to do. Perhaps other parts and pieces inserted into the system mix may have unknown problems and might contribute to some odd issue. I don't think from the current baseline that there is any great number of LP UT X58 boards that have a problem. Obviously this customer had a problem as he understood his situation. This leaves us with only two options really. 1. Try another brand just to see if there is some issue with another component in the configuration. 2. Buy another LP UT X58 since there seems no pattern of noise problems with the board as seen in general and with at least 4 boards I know are pushed or overclocked beyond normal specifications.

The e-mail was pretty telling. It first went from a tech support help desk, to a engineer manager, and then to an engineer who worked on the board, Robert. Small world eh? So this board the DFI x58 T3eH8 has a current output maximum of 364A. More than enough juice to handle any ammount of overclocking.

No word yet from ASUS, MSI, or another response from Biostar.

::EDIT:: I just got a repsonse back from Biostar,

The VRM Max. output current is depend on Max. CPU. So far Intel i7 highest CPU did used 135W, so the 130A did normal.

The broken english leads me to believe that they did not test the board for over 135W @ 130A.

Yeah, looks like a communication issue there. I just PM'd polygon and a Biostar rep at Rebels. Hopefully they can clarify.

For those who may be considering the Biostar x58, here's a nice overclocking thread over at Rebels:

and a general discussion thread on the board...

I just repurchased the x58 T3eH8 because I am confident that the power system is laid out to give great power to the CPU. I just had a shotty board. It happens. ASUS sent me an e-mail that said the information is proprietary, so now I'm waiting for MSI.

The only thing I didn't like is the Biostar BIOS from that board but if the max current output is higher than their rep will give me then it is probably a solid bet for decent overclocking.

I made a quick run at 4536 mhz with the biostar, the bios isn't holding it back. The mosfet coolers just get a little warm. Don't think there is any problem with the board power management....

pics please

thats a new rule here...

you MUST post pics of your setup in this thread.

like pics in general of the rig? or do you mean SS?

PICTURES. we know how they perform. lets see the hardware.

Didn't say anything about the bios holding you back from an overclock. I think the bios is fine for that, but it's not detailed enough for my taste. I want to be able to do more with my board the more I learn.

 

[freaksavior]

there is my setup lol

 

[The Haunted]

The kind of picture you want??

 

[n-ster]

Nice I wish I had that system... How much did the whole system cost in CAD (presuming you bought in CAD)? how bout just your i7 chip?
