Asus P6T Deluxe Discussion Thread

Anybody report on multiplier dropping from 21x under load??

Mine still drop in both LinX and Prime95 at 4.40 with HT enable when load temperature approaching 80'C, if I can keep it under 75'C then it remain at 21x.

[sbinh]

I'm on bios 0507 (dated 4/28) on P6T Vanilla. Good bios, boot 21/220 from (bios set), but my xeon W3520 still has all those features locked. It's not a big issue, performance-wise, but it blows my mind why Asus is still not doing anything about it.

Mind to share your settings?
I am still "learning" this board (P6T) and so far, cannot get it stable with BCLK above 180.

Temp. is rediculous..... Currently, have my i7 920 running at 3759MHz with max loaded temp on 1 core is 88*C (other 3 cores' are around 83*C-84*C) - with watercooling

[martinakerman]

If you Enable the CPU TM Function, does your CPU throttle down?

I think CPU TM Function works and throttle the cpu down when cpu reaches some limit temperature. ( but i thought we can enable o desable it)
I´ve never had my cpu above 77ºC.
The only time i saw my cpu below its x20 multiplier was at default bios setting, when idle multy goes down to x12.
But since i disabled CPU TM Function and C1E the cpu is always at x21, may be ´cos never gets more than 77ºC.
I thought Disabling : SpeedStep, C1E and TM Function will never throttle down.

Hmm mine will throttle down at a way lower temperature. What voltage are you using?

I think you are right. With the CPU TM Function disabled you should not get a throttle down. My self, I would keep TM Function enabled. And if you do get a throttle down, the fix would be at your cooling. I think it is like your dummy oil light on your car. It is not to limit your OC, but is just a safety switch.

I maxed out everything today with LinX + Prime95 + two loops of 3DMark06 (simultaneously) and had no throttle down at a MAX CPU temp of 76C. One day I am going to see if I can get it to do it. But, maybe it would just blue screen.

I fixed a computer with a Core2 that was throttling down. Big wad of cat hair in the stock cooler.

I guess if you fire that system up an turn it off when done you have your hands on the controls. But, many people keep their computer up for days.

Mine still throttles, even with TM Function disabled. What needs to be disabled is the OCP limit on Core i7 which the P6T Deluxe does not allow you to do. The Rampage II boards do allow it, as do all DFI, gigabyte and evga boards afaik. Major fail on Asus' part.

How hot is your CPU getting? Maybe you need a cooler change? What is your Vcore?

I ran this all Simultaneously and no crash or throttle down. I maxed out my 12 GBs of RAM Man. I only have Air Cooling so I take it EZ.

Its turboboost throttling not what you may be thinking. It's really not going to be an issue for probably 99% of the rigs being used since you have to be pushing decent clocks, voltage and temps under extreme load for it to happen.

Ah, if you are at a lower voltage and speed due to air cooling I don't think you will notice the problem. It is related to power usage, not heat (although heat can be a factor when the power is too high).

For example if I am at 200x21 with 1.49vcore, I don't see temps over say 80C, but if I run LinX the multiplier instantly drops to 20x.

I wrote this little program to try and keep a closer eye on the multi. At full load when Turbo mode first starts to cycle on and off, some tools might not accurately report your multiplier. The i7 Turbo tool uses high performance timers within Intel Core i7 CPUs to accurately calculate the multiplier at full load.

I was not 100% sure how that worked. And really still not. The Specs say 130W and now they came out with a thermal for the 920 of 67.9C. I used to the thermal days.

Personally, I really don't like the (Turbo Mode) 21x setting. I like it more straight forward. Can you use the 20x and a little greater BCLK? Or, does that impact your memory?

OK, this is a Rampage II Extreme thread. But, they are not running a Vcore as high as you are at like OC. You may want to look at this thread. Same CPU, and I think Power Phase.

Personlly I would perfer the 20x multiplier, but, it is way more unstable than 21x. That is why I am pissed off about this. And 21x would be every bit as stable as 20x if asus would enable the option to disable the TDC limits on the P6T Deluxe. Again, all the Rampage boards can do it, as well as all gigabyte, dfi and evga boards. Asus is the only one that restricts this option to their high end expensive boards. It's really starting to piss me off.

uncle:
That is a very good program and should demonstrate how unstable 21x really is on the p6t deluxe because of asus's limitations.

Real neat program. What does the rest do? Nothing at OpenLibSys.org. Does it just reset the counter not the hardware? Also, it seems to me that if you have turbo disabled in the bios the check box does not work.

working ...I ever try

[Zucker2k]

I'm working on eliminating EIST kicking in at a certain voltage/temp. In my experience, voltage seems to be the culprit. At 1.344v and 4510mhz, I get EIST kick-in at around 71c. But with 1.336v and the same 4510mhz, I get no EIST kick-in even at 74c.

For those trying to boot at 21x220 on the vanilla, try these:

pcie freq: 104-108
qpi/dram: 1.4 - 1.425v
ioh: 1.28 - 1.30 (very important in my case)
cpu amplitude is at 700 for all my stability tests.

A little stablity run at 4.4Ghz, I managed to drop volts a little bit.... so far so good.

[martinakerman]

YEAH!!!!!!!! TURBO BABY !!!

This is what i got after 1 hour of playing Call of Duty 5, i left this I7 Turbo program to see if my cpu throtthles down....

[unclewebb]

The Turbo tool is designed to keep an eye on the multiplier and is very accurate and very stable when all 4 cores are fully loaded. If you are running LinX or Prime then a 920 with Turbo enabled should stay locked at 21.0000 like it shows in Zucker2K's screen shot.

At idle, the Intel algorithm that I'm using has a few issues and can result in some random values. They don't occur very often but they do happen so I might try to filter those out. Anything beyond 21.0 with 4 cores and Turbo enabled on a 920 is obviously a mistake and would be easy to filter. It might be an idea to log all data to a file so you can go back and have a look or take the data into Excel for easier analysis. A dropout or spike for 1 second is normal but a constant drop below 21.0000 at full load is a sign of the Turbo cycling on and off.

The value in the MSR box is the multiplier that other programs like Core Temp read and display for the multiplier. It may or may not warn you when Turbo cycling first starts to happen.

The Reset button only resets the minimum and maximum values.

The Turbo Mode Disable feature can only be used if you previously enabled Turbo in the bios. It has no effect if you have already disabled Turbo in the bios.

Here is the Intel documentation that this tool is based on.
http://download.intel.com/design/pro...ots/320354.pdf

The value displayed in the Multiplier box is the average multiplier for the previous 1 second interval based on Intel's algorithm.

I got "boot block in file is not valid!" error

[ben805]

Hmm mine will throttle down at a way lower temperature. What voltage are you using?

1.40v @4.4Ghz with HT enable, or 1.46v @4.5Ghz with HT enable. Throttle kicked in when loading in both Prime and LinX, this doesn't seems to isolated to only LinX. I ran a series of cpu benchmarks from Everest at 4.51Ghz with HT enable and notice it score worst than 4.40Ghz, ran the monitor software and bench again, this really suck as the multiplier get throttle back down to 20 x215, my 4.51Ghz overclock practically became 4.30Ghz under heavy load...which is not good!!

Worked fine on my V2 save odd bootup issues until the bios was cleared and manually re-set. I also found that the G15 keyboard not being detected can be solved by setting the USB 2.0 speed to "Full" rather than "HiSpeed". Unfortunately, that lowers the USB speed from 480 to 12 Mbps......

[Formann]

I dont think OCP is the a factor when my multi drops. Also, i think this program might be too sensitive. Take a look at my max multi.

I have disabled EIST and C-states in BIOS, but the tool shows its enabled. But thats because the 21x multi uses Intel Turbo wich again uses EIST??

Unable to upload pictures.... bah.

I will edit my post with picture as soon as I install FlashFXP and find my logon info.

Meanwhile:

4009Mhz - 191x21

It definitely should not drop below 20 if you have it set to 21, if it is, that is either a reporting error or you have something else going on, possibly EIST, C1E, C-State or CPU TM Function. unclewebb already said there were a few issues with i7 turbo such as the high multiplier reporting.

EIST and all the other powersaving features is disabled in BIOS.
When disabled in BIOS, is EIST suposed to show as enabled or disabled in the i7 Turbo app?

Im still running prime, and since I last posted the i7 Turbo new reports 15.9x min multi.

I have been staring at the the program, and when the multi changes its only for half a second before its back at 21x.

EDIT: According to the i7 Turbo app my multi changes every single second when idle. Min 20.8 and max 21.2. I dont get it.

EDIT2: I just read unclewebbs post, so never mind
