upgraded CPU, PC boot problem.

December 30, 2010 at 03:08:07
Specs: Windows XP Pro SP3, 1.8 GHz / 2 Gig
I have a ASRock 4CoreDual-VSTA motherboard with a Intel Core 2 Duo 1.8 Ghz. This cpu came with the PC and works perfectly. I tried to upgrade to a Intel Core 2 Quad 2.4 GHz Q6600 CPU. When the PC now boots, it either freezes on a black screen with a blinking cursor or it freezes on the Windows XP boot screen and cannot boot into SafeMode. I have checked the ASRock website. The cpu is compatable with the board. I have also installed all the latest chipset drivers, updated the BIOS and reset the BIOS and loaded defaults in BIOS. The BIOS shows the quad cpu and the updated bios version. The cpu is not overheating, staying around 37 degrees. I ran the Intel
diagnosis tool on the quad cpu and it passes. I install the older core 2 duo and things working fine again. Any ideas? I'm going crazy here! Thanks.

The specs u listed is a mess, list them well(cpu, ram, board, video card etc). Did u try to clear cmos(by jumper or reinstalling battery)?

If you do some googling, you'll find numerous hits regarding instability issues with the Q6600 & 4CoreDual-VSTA. "Crossover" boards that have multiple support options (DDR, DDR2, AGP, PCI-e) are almost never a good choice. To make it worse, it's based on a VIA chipset. Looking at the specs, the PCI-e only runs at x4 & SATA is the early 1.5Gb/s version. You would have been better off buying a new board rather than a new CPU.

Thanks for replies. This cpu is listed as being compatable with this board. Just wondering why I cannot get it to work properly. As for my specs:

cpu: intel core 2 duo 1.8 Ghz
ram: 2 gig ddr2
video: radeon X1650
HD: 250 gig sata

The bios has been reset by jumper and removing battery,

Thanks.

Sometimes a board is listed as supporting a CPU, but there are often multiple version numbers. It is very possible you have an early version of the board and only some of the later versions may support some of the later processors fully. ((This is just a possibility, but not an uncommon one out there.))
Look at this board (w/graphics):

or this board -> better (no graphics though):

Thanks for the reply. I have put the Intel Core 2 Duo back in my PC. Working fine. I have had it with trying to get the Quad working on this board. Thanks for the board recommendations. I think I will purchase one of the boards you have listed. I thought this ASRock board was a good one, but I guess I was wrong. Too many compatability issues. I remember having a problem getting the video card to work with this board also. Thanks again.

That board is shown as a deactivated board on Newegg's site, it is an older board and is more limited in it's support. FSB1333 max, 1066MHz RAM max (not so much OC headroom), PCIexpress 16 slot 1x not 2x (might matter for gaming). Otherwise it is not too bad if you can get it cheap and should handle the Q6600 just fine (might even OC to 3.0GHz if you are even interested in that)

I like this board better though:

especially if the price is close (might OC to 3.6 with advanced cooling).

Hi. I bit the bullet and purchased the "GIGABYTE GA-G41M-ES2L LGA 775 Intel G41 Micro ATX Intel Motherboard" you recommended. I'm hoping things will work ok with this board and the Q6600 cpu. I cannot return the Q6600...the sale was final, another board is my only hope of getting it to work. Should a repair install of XP be fine after board replacement? I hate to have to format and reinstall all my programs. Thanks for all your advice and help.

It is certainly worth trying right from the beginning, if it boots to windows after that, immediately install the correct drivers for the motherboard. If it does not, you will be reinstalling. Back up your files first though.

Ok. I'll let you know how I make out once I receive the new board and hopefully get it up and running. I may be interested in OCing if possible, which I have never done before. Would it be fairly straight forward with the new board? Thanks again for the help.

For overclocking the P43 or P45 would be better but that board is not bad for OC'ing (I have one running a core 2 duo E7500 at 3.54GHz) but unless you are running a distinct video card it will become unstable before you get very high. Assuming you run it the way it is (nice CPU the way they ship it anyway) until you get a video card and read up on overclocking in the mean time. You will need a few programs: Speedfan to check internal temperatures and fan speed; CPU-Z to check the process, actual speed, RAM speed, etc.; and a stress tester like Prime 95 to test stability. You will need to preset a few things in the BIOS like:
PCIe at 100
Disable SpeedStep and all 'C states
And you will need to understand the math involved:
Your CPU will default to a Frequency of 266 MHz.
Now 266x4= 1066MHz FSB
AND 266x9 (your CPU's Multiplier) = 2400MHz = 2.4GHz
AND 266x3.0 (memory multiplier) = 800MHz DDR2 RAM (though a 2.0 memory multiplier is generally considered better since it gives you a 1:1 Ratio
To Overclock this I would look for a frequency of 333MHz since it will use your board's maximum FSB:
333*4 = 1333 MHz FSB
333*9 = 2997 MHz = 3.0 GHz
333*2.0 memory multiplier = 667 MHz DDR2 for a 1:1 Ratio
or
333*2.4 memory multiplier = 800MHz DDR2 if you want to run 800MHz DDR2's at their factory settings.
At these settings you will probably have to raise the CPU voltage (Vcore) a small step or two for a stable system. Many recommend setting the frequency from the start but holding down the CPU multiplier to 6 or 7 to test the board and memory at these settings and bringing the multiplier up a step at a time and bringing the Vcore up if needed as you reach your goal.

Hi. I have finally installed my new board and it's running the quad q6600 like a champ...no problems. I am now concidering overclocking it. The board has a utility in the bios to set overclocking options. I have no idea about overclocking. What could this cpu be overclocked at SAFLEY with the factory cpu heatsink? What programs will I need for monitoring and what options will have to be changed in the bios? Thanks for all your help, I would not be this far without your knowledge and input. here's a few specs:

board-"GIGABYTE GA-G41M-ES2L
ram- 2 gigs ddr2
video- pci express ati x1650
cpu- intel core 2 quad q6600

Most do not recommend the software overclocking (though theirs appears to be better than most), but that means you will need to learn a little about it first so start google-ing.
Please reread Post #12 where I basically gave you the information to overclock it to 3.0GHz which is where this board will top out (FSB1333 is supported max, if you went with the P43 board you would have had a little more head room for the future since it can handle FSM1600)
I say to Google 'OC Q6600 GA-G41M-ES2L' and just 'Overclock Q6600' and see what you get. You still need to begin understanding what the settings mean and the reasons you tweak them. And VERY important, watch your temperatures!!!
By the way, I assume you cleaned off the old thermal compound from the CPU and heat sink and applied new compound when you assembled this system (VERY IMPORTANT).

Hey. Thanks for the reply. I have cleaned the cpu and heatsink and applied new compound. Temps running fine as of now. I will do somemore research on OC before attempting. Thanks again for your info. I thought the q6600 I bought was faulty and it's not returnable, but it's working flawless on this new Gigabyte board. Thanks again for the board recommendation, you have been most helpful.

You are quite welcome. Enjoy.

Remember, if you save your receipt you always have the Intel Warranty if you have any major problems (as long as you don't fry it with too much voltage that is).

Hi. Thought I give you an update. I now have my computer overclocked to 3 ghz along with the ram at 667 mhz 1:1 ratio. The computer is running stable. I actually had to drop the vcore voltage a little to 1.2 V. Not sure why, but I watched a youtube video of a guy overclocking a q6600 and a gigabyte board and he dropped the voltage down. It's working fine though. I also purchased a coolmaster cpu cooler and installed it. The temp is running around 30-37 degrees idle and around 65-70 degrees with a 100% load. I'm wondering how much it can overclock? What are safe temps for this cpu? Thanks.

Your board tops out at 1333FSB and your multiplier is limited to 9 so you are at about the limit. Had you gone with the P43 series board you could have gone up to (in theory) 1600FSB so 400MHz x 9= 3600MHz or 3.6GHz with RAM at 400 x 2.0 = 800MHzDDR2
Your temps are good, just keep an eye on them occasionally during/after heavy use. Your Quad at 3.0GHz should be able to handle anything you can throw at it. You would have to have a monster video card before the CPU would be the limiting factor on games.
Thanks for the update and good luck.

Hi. The ram I have is 2 gigs DDR2 667 Mhz. I assume maxing out the ram at 8 gig using DDR2 800 mhz would improve performance even more? Thanks.

Your 32bit Windows XP cannot use more than 4GB RAM, in fact with 4GB installed, it will show only a little over 3GB so it really is not worth it, plus unless you use very large files or certain types of programs (CAD, Photoshop and similar) you probably will not notice any improvement from memory over 2GB with XP. As far as the DDR800 memory, your system is running at the Ratio of 1:1 CPU/RAM and for most experts this is optimal for your processor due to latency. Although there are some who disagree with this IF there is any difference, it would not be noticeable with your system. IF you were running Windows 7 64bit, THEN 4GB of RAM would be a major improvement and 8GB or RAM would be usable (though whether you will get an improvement with 8 over 4 will be determined by the programs you use) so purchasing the 800DDR2 in that case might make sense (you could always underclock it back to 667DDR2 if you wanted).
I guess you have been bitten by the bug.... save up.... you will probably be looking at online components (like most of us) and thinking about the next complete system you will build.... maybe that new i5-2500K ---- Hmm. Maybe next years will be even faster....

Hi. Sounds like I should leave it as is. Upgrading to 8 Gig or even 4 Gig doesn't sound like much of an improvement. You are right! I do now have the "BUG". It's fun to see how much "juice you can squeeze out of the orange"...lol. Thanks again for all your help.
