Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)

I think that Chike will be surprised with my 74 GFlops results when I used all available memory.

I'm surprised, about LynX's tera flop, the CPU is simply not capable.
With 4 flop/cycle theoretical max is 4 Flops x 4 cores x 3.4 GHz) = 54.4GFlops
4.3GHz Haswell with x2 faster and lower latency RAM (LynX 0.6.4):

@profJim
I'm not sure about this Refresh Cycle Time (tRFC) = 66.
This seems to be making my RAM slower.
Compare this screenshot with last one I posted where the Refresh Cycle Time was still on AUTO. (and that is the only change I made)





Change it back to AUTO again?

Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)

The following is from Lsdme's http://forums.tweaktown.com/gigabyte...t-vs-bios.html thread.

• tRFC Timing: (Refresh To Act Delay) Row Refresh Cycle Timing. This determines the amount of cycles to refresh a row on a memory bank. If this is set too short it can cause corruption of data and if it is too high, it will cause a loss in performance, but increased stability.

Using a higher numbered setting will help with stability if the previous setting was too low.

In your screen-shot in post #7 you said that Performance Enhance = Extreme was used.
The memory sub timings in post #17 look like they are identical to the timings with Performance Enhance = Turbo.

Change it back to AUTO again?

In post #4 you said that you set Performance Enhance = Standard and it looks like tRFC is automatically set to 60 or 66. If you use the Turbo or Extreme option, tRFC might be set too tight, that is tRFC will have lower setting and might not be stable.

I've found that some of Maxxmem2's results can often vary by 100 - 200 points or more, even when there are no bios changes. There are other memory benchmark programs but the memory tests are more involved or you must buy the software. Maxxmem2 is free and it's easy to run.

I did several Maxxmem2 tests (without rebooting my system) to show how the results can change.



#1 was run two minutes after I booted my system.
#2 was run three minutes after test #1.
#3 was run about8 minutes after test #2 when there was moderate cpu activity (approximately 25% - 40%).
#4 was run several minutes after test #3 when there was heavy cpu activity due to starting an anti-virus scan of my boot drive.
The #5 - #8 tests were later run when there was very low cpu activity and tests 6, 7 and 8 were run one minute after the previous test was run.

Oeps....after more than 6 hours Worker 1 failed on me.
This was first test from the list of 3 in Prime95...for what it's worth....
So I better put Performance Enhance on Turbo (instead of extreme) and try again...?

This default CPU lock?

Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)

Yes, rerun the test with Performance Enhance = Turbo.

Tell us the name of the Prime95 test, Blend, Small FFT or Large FFT.
From your screen-shot you ran the Blend test or you used custom test settings.

Your screen-shots will be easier to read if you crop the image to remove parts of the image that don't have useful information.
You can include multiple images in one post if you use the Insert Image option (from URL) when you use Dropbox or similar file sharing sites where each image will have its own web address.

Your Memset screen-shot shows the wrong memory speed; it should display 533MHz when your memory speed is 1066MHz.
This also happened in my screen-shot in post #15.

CoreTemp shows your cpu speed = 1999MHz using the 6x multiplier. We can only assume that this is the idle speed due to enabling cpu energy savings but we don't know for sure that your settings include the maximum 8.5x cpu multiplier.

If you don't include enough detailed information about your test it will waste your time and ours because we need to ask for additional information.

Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)

It was the first test in the list of four, in my version of Prime95 that is 'small FFTs'
CPU speed and RAM speed was indeed in idle mode since I stopped the test. (1 worker had stopped anyway).
All settings are as written in the bios template in post # 1. Only changed the things that you advised me to change.
Doesn't really matter that much now, I guess, since I have to rerun all 3 Prime95 tests overnight...

[profJim]

Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)

My older Prime95 version is 28.5

Small FFT: min FFT = 8 and max FFT = 64
Large FFT: min FFT = 128 and max FFT = 1024
Blend FFT: min FFT = 8 and max FFT = 4096

These values are displayed in the lower portion of the Run a torture test window when you click on one of test options.

What is the memory model?
Does it has EPP profile? If not see the specs on the sticker for voltage.

Kingston sold 2 nearly identical HyperX PC2-8500, 2 x 2GB kits:

• http://www.kingston.com/datasheets/KHX8500D2K2_4G.pdf - regular heat spreader
• http://www.kingston.com/datasheets/KHX8500D2T1K2_4G.pdf - 60mm tall heat spreader

There is no EPP profile in the SPD.

From the Kingston HyperX data sheets:

Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)



Today worker 2 failed on me after more than 6 1/2 hours with Performance Enhance on Turbo.
All other settings as above.
The RAM is indeed KHX8500D2K2/4G, the ones with the normal heat spreaders.
I cropped above jpg image and save it with Paint.
The Original crop looks fine but once inserted here it looks lousy.
Maybe I'm just too stupid to get this right or maybe it is because this forum reduces the Original 667 kB into 159 kB....?

A Prime95 error that occurs after 6 hours means that your setup is close to being stable (for that test).

I'd like to see an ET6 screen-shot to see if anything is out of the ordinary. I assume that you initially loaded Optimized Bios defaults before you made any bios changes.

About 18 months ago I tried using the latest and greatest version of Prime95 and had all sorts of troubles even when I tested it with my bios settings that had been stable for quite a while. If you want to try the slightly older version: https://dl.dropboxusercontent.com/u/...v285.win64.zip

I save my screen-shots using the PNG image file format because you can save the image file many times and the image doesn't degrade. I've been using IrfanView freeware for all my quick and dirty image editing and viewing. The attached screen-shot is a bit bigger than 1MB and I have it saved in my DropBox public folder. All I need to do is to copy the picture's web address and use the forum's Insert Image option where I paste the web address for an image into the From URL option and uncheck the box below the inserted web address. In post #25 I used the Insert Image option to include the two HyperX images from a google search and also included my Memset SPD image that is in my DropBox public folder.

I find the sensor display information in HWiNFO64 very useful while stress testing my system. You also have the option of logging some or all of the sensor data to a saved CSV file.

I'm just over 4.5 hours into my latest Prime95 Blend test madness using Performance Enhance = Turbo along with my HyperX T1 8GB @ 1080MHz, lowered my cpu speed from 4.012GHz to 3.825GHz and now the LinX and Maxxmem2 results are better.

BTW, none of my ET6 voltage settings will help you with your current stock cpu speed.

The RAM is indeed KHX8500D2K2/4G, the ones with the normal heat spreaders.

You need higher voltage then 2.1-2.3.

Customize prime test with FFT 384 (or which ever you get error with) for min and max FFT. Normally it will be the same FFT that fails, not need to wait 6 hours. If it pass 20 minutes than run the default range again.
I also set memory to little bit less than available (in tack manager, performance tab) to test as much memory as possible.

Re: BIOS tweaking or best BIOS settings GA-P43-ES3G (rev. 1.1)

With my EP45-UD3P, all AUTO settings for voltages worked fine in the M.I.T. section up to 3.20GHz. The OP's P43-ES3G motherboard is not as sophisticated so he probably can't copy my examples, even at lower cpu/memory settings. We both have nearly identical 8GB memory kits, but I have never needed more than 2.10 volts for my memory in my P35-DS4 and EP45-UD3P systems, even with 4.0GHz and higher overclocks..

I was thinking that the smallest possible CPU Termination (aka VTT) increase might help with stability, even though his system isn't overclocked.

Almost identical only that one require 2.2v and the other 2.3v, small difference, OP is at 2.0v.
Are we trying to save power or stabilize his system?
