EP45-DS3L System freezing

[stamfordjim]

hello all,
My problem is an immediate system freeze with any of three decent grfx cards. With a much older card the system is quite stable while running Vista 64 except for these symptoms with various tests:

With 8 gigs of ram Prime95v.25.9 build 3 (64bit) freezes almost immediately.
With 4 gigs (various mixtures of the sticks) it always seems to pass.
Memtest85 2.11 and 2.11a both freeze with "loading ....." screen (4 gigs,8 gigs, doesn't matter)
RightMark Memory Analyzer 3.8 doesn't run - mma.exe errors with "Error initializing Sysinfo library. Failed to load RTCore64 driver." The small test window launches but nothing happens. Maybe an issue with Vista 64?
Windows memory test passes repeatedly with two different sets of sticks - 4 gigs
Any overclocking set with EasyTune6 causes either a very quick system crash or even a boot failure.

I'm pretty technical (since early Apple II days), built lots of machines but not exteme tech. Here's what I built:
SeaSonic S12 II SS-380GB 380W
GIGABYTE GA-EP45-DS3L intel p45 chipset w/sound, ethernet
INTEL Core 2 Duo e8500
2 G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 - 8GB total
Maxtor 6L300S0 7200RPM SATA
LITEON iHAS120 DVD
VisionTek 900244 Radeon HD 4870
Also have a SATA card to connect external SATA raid box but removing the card didn't seem to have any impact.


No overclocking, 'safe' settings used. Vista 64 Ultimate. BIOS and all mobo drivers updated from Gigabyte; OS is completely updated.

With the Radeon 4870 installed the system freezes up very quickly - sometimes before the boot/login process completes, always within minutes. Could not immediately acquire the Visiontek card so I tried a 4870 from Sapphire which also froze. I returned it and ordered the recommended Visiontek.

With an old ATI Radeon X800 card the system is very stable.
Before each attempt to install I have used a driver sweeper to remove any ATI drivers, set the video driver to default VGA 800x600.

Identical issues with PNY NVIDIA Geforce 8800GTS 512. Newest drivers, Drivesweeper to cleanup before installing. NVIDIA works fine in older P4 w/ASUS mobo.

I replaced the psu with Antec Earthwatts 650. No change at all.

No idea how to troubleshoot - no log files or events that seem relevant and apparently Vista 64 doesn't offer the handy 'try to find solution to unplanned shutdown'.

I actually have another psu arriving tomorrow (certified by ATI for the 4870) but don't expect any benefit; just going through the 'compliance' process.

HELP!! :) - any insights appreciated - here are the BIOS settings - I press F6 on the Tweaker settings so should be 'safe':

RightMark Memory Analyzer 3.8 doesn't run - mma.exe errors with "Error initializing Sysinfo library. Failed to load RTCore64 driver." The small test window launches but nothing happens. Maybe an issue with Vista 64?

Yes, this is a x64 issue, you need a signed driver for Vista to run the program, something the maker of this software cannot afford yet or does not wish to pay for for some reason?

Here is a Signed driver for the program, rename the original File to RTCore64.sys.bak and then copy in the new driver and the program will run properly >>>
RightMark Signed Driver.zip

Memtest85 2.11 and 2.11a both freeze with "loading ....." screen (4 gigs,8 gigs, doesn't matter)

Please use the latest Memtest86+ >>>
Memtest86+ - Advanced Memory Diagnostic Tool

Your error however sounds like a widely know error, you are using AHCI Correct? Sounds like it. Well this issue is caused by AHCI, to run Memtest86+ you will need to change that setting to IDE in the BIOS to run Memtest, then change it back before you load windows. Don't forget to change it back!

8GB of memory is going to need alot of different things changed compared to 4, that is why you may be passing prime with 4GB but not 8GB. The same settings are not going to work, if you knew that then ignore me, just getting that out there incase you didn't.

All overclocking should be done in the BIOS, not with Easytune. And even if you do use Easytune for a small test of changing FSB a bit or something like that, do not use the Save button, use Apply only. I do suggest overclocking be done in the BIOS, but doing some small test in Easytune is fine

No overclocking, 'safe' settings used. Vista 64 Ultimate. BIOS and all mobo drivers updated from Gigabyte; OS is completely updated.

What do you mean by "Safe"? You should load and apply Optimized Defaults, not FailSafe if that is what you meant. After you switch between 4GB and 8GB you should do this, that way all those Auto settings you are using are properly set

Sounds to me like a PSU issue as well, Glad to hear you do have a certified PSU on the way just incase it is not

Here is what I would reccomend for 8GB, as a optimal starting point. Please check your ram sticker for voltages, or Tell me the model #

Thanks for insights and no, was not aware of the differences needed for 8 gigs. Tried the settings several times with minor changes where you indicated possible ranges of values. No progress really; prime still locks within 3 seconds. I got Memtest-86 v3.5 and that loads and supports dual-core. I am taking each memory stick and testing in each slot - should take 16+ hours/1 hr for 2gigs; about 1/2 done. It cycles each test with each cpu two times; no errors so far. After that I will try the new psu altho the 650w is new and is intended for quad/dual core and hi-end video. Jus that the new one is certified by ATI for the Radeon. So far I am still working with the old ATI X800.

[Lsdmeasap]

You should use Memtest86+, it is newer and the most up to date. >>>
Memtest86+ - Advanced Memory Diagnostic Tool

Memtest86 3.5 is old

If you still have issues please post back the FULL Exact settings you have set that fail and I will advise back

Since you say Prime locks up in seconds but you are going thru hours of memory tests already without errors I would venture to say you need some voltage adjustments more then anything else.

Likely MCH Core, Vtt and or Vcore, Auto is not always going to work especially when you put a strain on the NB like you are with 8GB.

But of course in the end, it could be the PSU Issues. Since you already have a new PSU I would stop where you are and put that in, and your new GFX Card and go from there

[stamfordjim]

OK - very good progress. Thank you! I added new psu and Radeon 4870. Initial failure. I changed some settings, several times with failure upon opening any app. Then tried the following and remained booted after loading CCC from ATI then while playing a movie in WinMedia and second movie in Nero simultaneously. Left them running for about 45 minutes, no errors, hit the web, email, loaded EasyTune (previously that locked the sytem) and Task Manager and Gigabyte System monitor all simultaneously. Closed everything, ran prime95. Previous efforts locked up at 3 seconds - this time it lasted 6.

Just a guess here, but the fact that the system is more stable with the old video card makes me think that this may be a heat issue. How big is your case, how many case fans do you have and how fast are they? What is the ambient temperature in your room?

[stamfordjim]

Thanks - during all of this both covers of the case were removed; now with the covers on, with the Radeon 4870, the monitor shows the CPU at 33-34 C pretty consistently, the system at 37-38. Actually I have now been running for about 8 hrs and the only thing that has made the system freeze is the prime95 stress test. Also, no oc on anything - just trying to get stable.

Looks good, sorry for the late reply!!

You can now start to tweak your memory then, I would start with static tread (tRD) MCH Core voltage may need to go back up if you want to lower tRD which is advisable as this has the MOST Impact on system memory performance and 10 is very loose >>>
