Does Celeron D 320 2,4ghz support HT?

[ifebb]

Hi guys... i'm newcomer to the overclocking world, and as my first experiment is my 2,4ghz celeron with MSI 865PE Neo P mobo, 2x256 DDR400 Kingston, HIS Radeon 9550, 80g Maxtor... I managed to get to 3,22ghz by changing fsb to 180... On system details from PCMark04 there's a line that says "Hyper Threading support : disabled" , but infact in my bios, there's no HT option... before i use Prescott 3,0ghz on that mobo, the bios have HT enabled/disabled option... so, does celeron D really support HT or there's something wrong with my mobo? i try to get msi live update for the bios, but my bios is the latest they have...
one more thing guys, why in cpu-z on memory section it says that fsb:ram 4:5 ?? at the moment ram freq already 225, and i dont wanna risk my memory to get higher, but i really wanna to get fsb to 200...
anyway guys, its really nice being here and thanx for your support.....

The celeron does not support hyperthreading, thats restricted to Pentium 4 'C' (800fsb northwood core chips) and the P4 'E' (prescott, all but the 2.4ghz prescott has ht)
pretty much anything on the 800fsb or more will have HT.
Running ram at 1:1 is usually beneficial, running 4:5 means your ram is running quicker than your fsb usually has very little gain and can even be a loss like that

If you have the Kingston value ram, your probably maxing out the memory. Run 1:1 like keith says... That CPU should do at least 3.4ghz without breaking a sweat. Shoot for 3.6ghz... At 1:1, your memory will be at 200.

Yeah theres little point in running ram faster than the fsb as it's thehn limitted by the bus, another bonus of the A64's onboards memory controller
and was 3.25ghz the best you could get out of the celeron? could it be because the memory is running on the higher divider? As mine, a friends and a few people on here celeron's managed 3.6ghz, mine and my friends with stock cooling and no extra voltage.

Im not sure on settings as my Asus(i think) P4S800-MX board did all the work for me and allowed me to choose 2.4 or 3.6ghz but iv'e been running it for almost a month now i think at 3.6ghz on stock cooling etc and it is great

I don't think any of the celeron line support HT and probably won't or atleast for some time. Im also using Kingston Ram(256mb Single Sided Module) which is rated at DDR400 PC3200.

well guys, finally i got my problem solved... before my ddr clock setting in bios is "auto", so when i increase the fsb, the ddr also increase in a 4:5 ratio, then i change my ddr clock to 166, and voila... when i increase fsb, the ddr increase in a 1:1 ratio!... at the moment i managed to get in windows in 3,6ghz, but when i play some games (usually FM2005 and NFS underground) sometimes it hang.. when i lower fsb to 185, it run smoothly... dont know what the problem is... should do prime95 test first i think to find out exactly what's wrong....
one more thing, what does "spread spectrum" mean? it has option enabled/diosabled on my bios...
thanx again guys! it really gives me a lot of experience watching the forum...

[ifebb]

almost forget one thing, or maybe because i placed my computer on a room without air conditioning that cause the problem? as fyi i live in indonesia, which is the temp all year is 32-35c ...

Spread spectrum varies the clock speed slightly to try to avoid EMI (Electro magnetic interferance) and can have adverse effects on stability when overclocking, so try it with it off until you find your highest stable overclock.
Prime95 will tell you for sure if a chip is capable of a clocksped at the set voltage, if prime95 passes and a game cause instability then the likely cause would be heat due to the extra produced by the video card, what cores temps are you currently seeing? Prescotts start to throttle at around 70°C so try downloading throttlewach from the download section and check this isn't happening
All that may be needed is a little extra vcore voltage if temps aren't too high.
