Change RAM speed

Bobo · 11-28-2004, 09:56 PM

How do I change the speed my RAM is running at? I have a Presario Athlon 64 3400, with an unknown mobo and 512MB PC3200. The FSB is (supposedly) 400MHz, but my RAM is running at 333MHz. Any ideas on how to change this?

Also, on a computer info screen in the control panel, it said that my CPU is 1.6GHz. I know that the Athlon 3400 is NOT 1.6GHz.

Cant help until you nail the mobo down for us (http://www.cpuid.com ... grab CPUz and look under the mainboard tab ... at the least ill need to know the chipset).

Ok here's an analysis:
- Athlon64's dont have a FSB .. they have a Hypertransport ... a small semantic difference perhaps but for starters I can tell you if your HT is running 400MHz then you're machine is already underpowered to crap. The A64-3400 is a Socket754 part and as such the chipset supports 200,400,600 and 800MHz Hypertransport speeds. For starters youll want to jack the Hypertransport back to its proper 800MHz. Now there is one caveat ... if you have a nForce3-150 board their the maximum HTT is 600 (not 800).
- Now since your Hypertransport is set for 400MHz and you have a OEM bios (cuz Compaq/HP make their own), i'll surmise that your core clock is set incorrectly as well (CPUz can tell you all that funky information .. look in the box labeled HTT ... it should read 200MHz or so)
- About the RAM .. if Compaq gave you PC2700 (DDR333) memory then the memory will run at 333Mhz (since the BIOS wont often allow OCing). Only thing you can do is upgrade the memory.

Like with the 400MHz Hypertransport ... this could just be the effects of Cool n Quiet ... why use CPU power when you dont need it. Try reading that display while you're doing an intensive test of some sort (i suggest ParticleFury, google it, its free)

Wow, that was easy. I had downloaded Everest, and it could not tell me what mobo i have. But according to cpuz, I have an ASUSTek Salmon 1.03 with a Sis 760 Chipset. I had figures out the latter, just by looking inside the comp.

I dont know where I saw the 400MHz FSB, I think it was on the HP website, where I bought this comp.

Under the CPU tab on cpuz, it said the CPU core speed is 1804MHz, and the HTT is 200.9MHz

Under the memory tab, it said the RAM freq is 164.4 MHz. What a waste! I could have PC2100 for a better price and the same performance.

Compaq gave me PC3200, I made sure of that.

Could all of this have anything to do with having an older HD installed???

How do I go about "jacking up" the HTT?

Yeah, when I ran Particle Fury, the CPU speed went up to 2.4 GHz

Is there any way I can keep it there?

P.S. Particle Fury is hypnotic!

How do I go about keeping the CPU and RAM running at top speed?

This really pisses me off, cause I like to have my computer in tip-top condition.

Disable Cool n Quiet and youll be running full bore all the time

(you'll have to look in the BIOS for the Cool n Quiet feature)

How do I get to the BIOS in XP? I have the diagnostics screen enabled, but I have yet to get into the BIOS. What tab would that be under?

Thanks

Bobo · 11-29-2004, 02:15 AM

And how do I get a picture under my name like you have?

Don't laugh at me, I just joined today. And my skills are more in computer hardware than software.

You do it at the beginning when you turn your computer on, press Delete or F1 or whatever it tells you to press. Just be careful in BIOS so you dont really mess stuff up.

Goto your User Control panel, under User Options i think. I have no idea (cant remember)

Bobo · 11-29-2004, 02:27 AM

I tried that, F1 only takes me to setup, and I didn't see anything about that. I can try again, though

I have 3 HDs on my comp currently, one 7200rpm 40gig, the other two older ones from previous comps, about 10 years old. Will they put a limitation on anything I do? Besides the read/write speed

Thanks
