System Name | AMD |
---|---|
Processor | Athlon x2 7750+ BE |
Motherboard | Biostar A770 A2+ |
Cooling | Stock Phenom cooler |
Memory | 2GB Geil BlackDragon + 2GB OCZ Platinum DDR2-800 |
Video Card(s) | nVidia 8800GTS EXO |
Storage | 500GB |
Display(s) | AOC 916Swa |
Case | Frontier Achilles |
Audio Device(s) | Realtek Azalia |
Power Supply | XFX 450W (SeaSonic) |
Software | Win7 x64 Pro |
So, i had this system:
ECS A780GM-A (1.1)
AMD Athlon x2 4000+ (2.1GHz Brisbane with FSB clocked from 200 to 220MHz)
(Phenom II stock cooler)
2GB Geil BlackDragon
Point of View 8800GTS 320MB EXO
160GB Maxtor + 330GB 2.5" portables (80 + 250GB)
Asus DRW-1608P2S
Saitek Cyborg Keyboard
SteelSeries Xai
Canyon CN-WF511 (Realtek RT61) WLAN
Frontier Achilles chassis with LC-8400BTX 400W PSU
once, when i sold my radeon 4650, before i installed my (then) new geforce 8800, i tried to clock my integrated radeon 3200. best stable speed i had got was 650MHz.
any speed above that made pc restart on windows logging in.
then, few days ago i bought another 2gigs (2x1) of OCZ Platinum DDR2-800.
first thing i tried was to clock my athlon from from 2310MHz to 2394MHz to get 399MHz on ram (CPU/6). same thing as when overclocking my integrated radeon happened.
my pc restarted, sometimes while logging-in to windows, sometimes while booting windows, and sometimes even during bios post-message being showed.
BUT, this time reverting fsb speed to 220, 210 and even original 200MHz didn't helped.
first thing that crossed my mind was that mainboard is damaged (because of previous integrated radeon experience), so i changed it to Biostar A770 A2+ - problem continued.
i've tried putting my friends old Gigabyte GeForce 7300GS (128MB DDR2-800 - passive cooling), installed XFX 450W (XFX-P1-450S-X2B9) PSU, tried removing and combining my rams in different ways (all 4 in all combinations, 1 ocz+1 geil, 2 geil's, 2 ocz's, 1 geil, 1 ocz), nothing helped until i discovered that underclocking my cpu to 1500MHz prevent the problem happening.
also, setting cpu voltage to 1.4V (default is 1.25/1.325V) makes it stable on 1.8GHz.
so, i changed cpu to athlon II x2 7750+ black edition (AD775ZWCJ2BGH).
again, restarts happen - no matter is it windows xp or windows 7, after loading text mode drivers, boot screen shows up for a few seconds, then it restarts. xubuntu freezes on start of loading live user. i have also tried latest bios's for ecs board, biostar board, pointofview gpu and gigabyte gpu, no use.
i presume that underclocking my cpu would again prevent restarts, but only components i didn't change are chassis, dvd-rw, hdd (if you count ram-setup variations) and ide/sata cables. i even tried unplugging my mouse and/or keyboard, no use of that too (restarts too), both old and new power-supply cables, and 3 different electricity jacks.
again - i changed cpu, gpu, mainboard and psu.
my current setup is:
biostar a770 a2+
athlon ii x2 7750+ be with phenom stock cooler
1gb ocz platinum ddr2-800
gigabyte geforce 7300gs
160gb hdd
asus drw
saitek cyborg keyboard
canyon wlan
frontier achilles with xfx 450w psu
bios info shows:
CPU Vcore: 1.31V
NV voltage: 1.10V
+3.3V: 3.36V
+5.0V: 4.94V
+12.0V: 12.28V
DDR voltage: 1.87V
HT voltage: 1.21V
5V (SB): 4.70V
bios battery: 3.37V
CPU temp: 28°C
does anyone know would could be the problem, because only idea i currently have is my flat's electricity installations:S (but all other devices work fine, including my laptop!)
P.S. i underclocked athlon ii be to minimal 1600MHz (without changing voltage), and restarts stopped
