Celly 800 - Follow up

[saytan]

well i removed my RAID array (damn thing was rubbish anyway) and im sat here at 1208mhz, 151 FSB, 1.9v (Page_fault_in_no_paged_area BSOD at 1.85 during boot)

heres a couple of sandra benchies, from an old 2001 version

havent done membench cos im at CL3 "safety timings" (a valuable practice when trying to push a CPU imo)

Good but I think I asked this but why not going CAS2 raming it'll speed it up alot more than you think. If it won't work can you adjust the I/O voltage?

[saytan]

im at cas2 now

was using cas3 to check that ram wasnt holding me back

vio cannot be adjusted on sa6

Cel 800 cdo is a sweet chip isn't she. Glad to here you got it to the 1.2. Impressive what a litte half cocked chip can do. I thought the first time she booted at default at 133 that maybe they mixed up chips and i got a gig instead. Love to see what some watercooling could do to this chip with this stepping since mine post and ran at 166 default voltage if only I had the dividers. Could put it above the 533a and the 300a as the best o/c intel chip. Atleast the best coppermine anyway. I rewarded my chip with dumping the geforce2 mx and picked up one of those msi gef2 ti with 4ns ram.

i found a few instabilities


i got a typical heat-lockup in RTCW after 30 mins or so and C&C tiberian sun crashes when i try to use weapons at 1200+


im going to get a better HSF (got my eye on the globalwin SAK-38) which should fix the RTCW thing (load temps are peaking at 50-ish

the tiberian sun problem i cant see any fix to other than using CPUFSB to change the speed down to 1120 or so before running the game

Hymm that is a little high I am using an alpha and it more than does the trick without being to loud(I am using only standard paste but I would grab some silver it can only help) .Once you switch HS/F drop the v's i remember when i was burning her in I had the voltage way up at first cause I figured It was logical that the cpu would need it but it would only run stable through 3dmark and prime when I dropped her to default. Totally blew me away. It even ran at 1.7 but I figured deault was fine and my temps were low enough. You could try setting ram down to cas 3 and/or put the timing to normal. Agp for me was 128 found that number always worked for me. If you get her up agian at cas3 run 3dmark if she finishes. Let her go for a while and give that chip a good burn with it on a loop for a couple a days,some even go for like a week. Then try upping to cas 2 again and run prime 3dmark. If she completes on prime fine but not 3dmark then vid card or ram could be the pest, but I believe most crucial will do 150 cas3 at least. Of course it may be the cpu since no 2 chips are exactly alike. So don't rush out to buy other parts just for the 1.2, save your cash and meet me in soon to be tually land.1066 at 133 default stable ain't nothing to be ashamed of at all. Great overclock

damn that makes my Clock Look sad.. :(

Freak, no overclock is bad every mhz counts.

Thats great but heat is definitely a problem you can cool that down with a Volcano 6cu+ I'd bet since it is very cheap like 14.00 + S.H @ http://www.sidewindercomputers.com/ Most likely if you use ASII and lap it, it'll cool down to lower to mid 30's full load or something.

hmmm


how will that 6cu+ perform if i remove the delta 7kRPM fan and fit my 4800rpm/26CFM ystech?


edit: just negotiating to buy a used, lapped alpha PEP66U for a very cheap price
