I still have problems with my homebuilt PC

[badge]

I'm fortunate, I have a lot of 'spare' parts to work with. I can easily swap out RAM, MB's, CPU's, PSU, HD, Otical drives, whatever. Having this versatlity is the key to troubleshooting my many systems.

OK. I'll first try to bumb up the voltage on the memory to 2.1V.

The timings are on BIOS default. But when I change it to manual then the timings are represented in a way that doesn't match those timings you tell me about. I'll write the timings down as they appear in the BIOS, but otherwise leave them as they are for now.

I'm sorry I'm so difficult and helpless, I just don't know much about this whole thing and I'm piss scared that I might ruin something permanently if I set something in the BIOS wrong. 🙁 Thats why I don't proceed with these things untill I'm totally clear and what to do and how to do it. I just don't know how much those blocks can take.

Yeah, if the timings are at CAS 6 LAT your RAM could be causing that error message because of it. CAS 5 or CAS 4 would be more withing specs as far as how the RAM is holding data and communicating with the processor. The Microsoft link also mentions defective Video memory. I would just check the video card by installing it in another machine.

Once you set the memory adjustment interface to 'Manual' you should be able to enter the 5-5-5-15 valuses on your keyboard. Then save those values and 'save and exit' the BIOS.

I don't know where to put the 5-5-5-15 values...as the BIOS seems to use a different 'counting' system for the timing. Maybe its the same. But here it is:
-------------------------------------------------------------
Configure DRAM Timing by SPD [Disabled]
DRAM CAS# Latency [6]
DRAM RAS# to CAS# Delay [6 DRAM Clocks]
DRAM RAS# Precharge [6 DRAM Clocks]
DRAM RAS# Activate to prec [15 DRAM Clocks]
DRAM TRFC [38 DRAM Clocks]
DRAM TWR [12 DRAM Clocks]
DRAM TWTR [12 DRAM Clocks]
DRAM TRRD [12 DRAM Clocks]
DRAM TRTP [12 DRAM Clocks]
--------------------------------------------------------------

Looking at it I'm guessing that I'm suppose to put 5-5-5-15 into the first 4 lines, is that how this works?

Absolutely, enter 5-5-5-15 where 6-6-6-15 is currently entered. The other values should be set to auto, just leave the other values alone for now. Be sure to save and exit.

CAS LATENCY = 5
CAS DELAY = 5
RAS Percharge = 5
RAS Active to PREC = 15

If you can set those last 5 values to auto, do so.

 

[Jacob Collstrup]

Well the auto is for either ALL the timing or none, so I guess I'll just leave them as they are...
After setting the DRAM timing I'll try to stress test the computer.

Yeah, see when you tell me your system crashes when you try and run software, I immediately say...RAM causing it.

 

[badge]

The voltage too. Bump up the memory voltage to 2.1. Save and exit.

 

[Jacob Collstrup]

Ok...voltage has been upped to 2.1V and timings have been adjusted...my computer scored some 8000+ points in the 3Dmark 2006 test!!! 😀

So does this mean it works now, or should I try some more tests and if so, which tests should that be?

Jacob

Just overall stability and NO system crashes is what you are looking for.

Check if your Windows is corrupt. Load a LiveCD of some sort of Linux.

 

[Jacob Collstrup]

Well...it still doesn't work!!!

Now it won't boot up anymore, it seems...the fan on the graphics card just goes to maximum speed, but there is no screen image. I guess the video card is defect! It was close to booting up properly, but it decided to bluecsreen in windows!

I guess the video card is done for. I'm gonna try and see if I can borrow a PCIe-16 gfx to substitute.

Could this by any change be caused by something else?

Jacob

 

[Jacob Collstrup]

The graphics card wasn't defect when I got it, at least not completely defect. Could a weak powersupply do this to the graphics card?

I can't find a graphics card that I know works, so I can't even check if the mainboard is ok....
