Higher temperature and BSOD after RAM upgrade

[p5qse2]

Hello i just upgraded from 4GB to 8GB on this old computer running Windows 7 64bit. Now i have issues with temperature and frequent BSOD. I dont know if i have to make changes to BIOS or if my motherboard dont like the new RAM. I just bought the cheapest RAM i could find. Do you think i should try change to a different memory brand or may it be possible to change some settings in BIOS? Here i have included a recent log from CPUID:

Do your research for compatible ram with your motherboard, return those modules

Change your multiplier so the end-result for memory is not 400 (DDR2-800), but something less.

Or, simply lower FSB speed from 266, to something like 250. (that is basically a slight underclock of the CPU)
That memory might simply not work correctly at advertised speed, especially if you said it was "very cheap"

Alternatively, try the 2.5x multiplier (267x2.5 = 667) instead of 3.0x (267x3.0 = 800), your memory will be slightly slower but the computer might return to stability.

Mismatched ram would be my guess. I even if the model numbers are identical, sometimes the revisions are not.

Ive had this with Kingston ram in the past

Don't run with XMP, set your ram timings manually in the bios and see if that helps

I tried to change some BIOS settings, but then screen goes black and computer turn off after 20 sec. Then i have to reinsert BIOS battery. Dont know what im doing in BIOS. However i found a setting "Row refresh cycle time(tRFC) changed it to 40 and it seems like windows is loading much faster now.

FSB speed is this FSB strap to north bridge?
Alternatives are: Auto, 200, 266, 333, 400

And this is the other setting?
DRAM Frequency:
Auto, 533, 639, 667, 709, 800, 852, 887, 1066, 1200

Don't run with XMP, seriously your ram timings manually in the bios and see if that helps

Kingston went from being the most compatible to one of the most tempermental, I prefer mushkin overall for that.

Seems to be working fine now. I put BIOS to auto settings. Wish i could see exactly what those settings are set at. Also ran memtest and nothing wrong with memory sticks. I will buy some high quality thermal paste and see if i can get cpu temperature down its a bit too hot, 45-46C at idle.

Download CPUZ and you can check your timings and speed. https://www.techpowerup.com/download/cpu-z/

You added two Dimms, which upped the current drive level for the memory controller.

So it ran hotter.

That's pretty much normal, IMHO.

Those Dimms report 8banks, which are lower capacity chips; you might get some lower temps by replacing them with larger capacity chips, If your mobo supports them.

That CPU's default is 266 (333 and 400 are overclocks). In that generation, FSB speed is linked to CPU speed, so if you change it, you also change the CPU clock (and it might not like that)
Basically, if you somehow manage to get it to run at 400, that would been 3600 Mhz max speed, it runs hotter than the sun at that speed. But it can be done with a good chip...
So don't touch the FSB, leave it at Auto or 266

Instead, those RAM frequencies are various multipliers (seems that your bios made it easier, instead of using 2x, 2.5x, 3x... etc., as RAM must work in sync with the FSB (that was the architecture back then).

533 = 2x
667 = 2.5x
800 = 3x
887 = 3.5x

I have no idea what others are, half-steps ?

In any case, if your RAM and CPU gets too hot at 800, simply downclock it at 667... the difference in performance will be minor
DDR2 uses 1.5v at JEDEC speed (667 being the max), make sure you set that one. SPD might have set it to 1.8v, causing it to run very hot.

Of course, trial and error is your best friend.
Don't be afraid, you won't burn anything by downclocking and downvolting. It's the other direction that causes magic smoke
The worse that could happen is the computer not booting or crashing in Windows.
