I currently have the following combo:

AMD 700 at 1000MHZ and 2.05V
MSI K7PRO S6 R1 -110CG
256MB 2-2-2 PC-100 SyncMax RAM
V5 5500 @166MHZ
Seagate Barracuda ATA66 7200RPM
CL PC-DVD 20x/2x
Phillips CD-RW 2x2x6
SB LIVE! Value
Enermax EG-451P-VE
Alpha Cooling the CPU
Two RDJDs cooling the V5 5500(not to mention they make my ears bleed)

For the life of me I can't get this system stable enough to play games. I let it burn in today for about 5 hours doing nothing more than cracking for RC5. I got impatient as I waited for my NEC 9716 to finally be reformatted so I rebooted my 1GHZ system and it froze on startup. I'm typing this right now at 1GHZ. The temp is extremely cool on the CPU. It's amazing. My 550@800 Classic would burn my finger when I touched the core, but with this baby I could keep my finger on it all day. THe more voltage, the more stable. I'm maxed out as it is.

My question is, why does it do RC5 for so long, but not play any games?

Thanks,
Paul

Does it run stable not overclocked? Maybe games are more intensive then RC5.

My RAM was advertised as 2-2-2 RAM, so I assume it would work at 2-2-2.

My video card works at all other speeds (950, 900, 850, 800, etc)

If your system runs stable at anything lower then 1000 it meens that the cpu can't handel 1000 even if it's cold enough. It's probably not getting enough voltage.

Just because it can run RC5 for hours doesn't mean that it is stable for everything ,games will place a greater strain on your system so may show up new problems ,try reducing the clock speed of your cpu.Also don't forget that the graphics card will be adding extra heat to your case when playing games.
BTW RC5 uses the intger side of your cpu ,games will use the FPU ,hence this could also show up different problems.

Also remember that your AMD CPU does not have an internal diode to measure the temperature. Even though Intel CPUs do have it, the diode is not exactly correct. Just because your temperature readings are low does not mean that the internal temperature of your CPU is low since your probe is on the outside of the CPU.

When doing Photoshop, I have seen my Intel CPU run at 50C under load, but then temporarily spike to 70C, before dropping back to 50C. I would bet that during games, a temporary temperature spike is getting you.

Yes, you have an Alpha. They work great. But air cooling can only get you so far. Then again, it is winter. Stick your computer outside on a below freezing day and see what happens. :) On second thought, condensation or precipitation may get the better of you. :)

shiznut123,

You're not supposed to overclock:)

lifeguard1999,

I know that the readings on my mobo are false. This is why I touched the core. I'm too cheap to buy a thermal probe.

gfgray,

Enermax EG-451P-VE = 430W of power supply fun.
