hello there i've asked a couple questions on here about various things. latest question was about my video card evga gts 450 couldnt play even on low resolutions. well i think i mighta figured it out i just did a cpu test online and it said my processor was only clocking at 1000mhz. now usally that pertains to the fsb and to change that its in bios. well in my bios i have no option to change any tiimings or fsb multiplier or anything. my system pretty much is an acer x1200. ii ripped it all out of the slim line case and put it in new case. its as follows.

mainboard: Acer WMCP78M
processor: athlon 64 x2 5400+ 2.8ghz
memory: 4gb ddr2 800
video card: evga gts450 1gb with free performance boost
power supply: cooler master xtreme power 600 watt
hdd: hitachi 180gb
os vista 64 bit home premium

my question is, is why is only saying my processor is a 1000mhz when its 2.8 ghz. i think that may be the cause in my hardcore lagging of games. like i said i have no option in bios to change fsb or timings. since this pc was originally prebuilt is there an option hidden in bios that i can open. the bios verion is phoenix technologies R01-B0. PLEASE HELP ME SOMEBODY MY TECH LEVEL IA NOT VERY HIGH BUT A MODEST LOW TO MEDIUM

You used an onlien program to detect yoru processor frequency? (is that even possible?) Download CPUID immediately, and post your CPU results from that.

Your cpu clocks itself down to save power when not in use.

it still shouldnt read like that in cpu-z though should it? i bet you thats whats causing the lag in my games. i'm only like 10 frames a sec even in half life 2 episode 1 and it should blow that away left for dead 2 for that matter same way

Your cpu FSB multiplier is set to x5 in your bios. So 5x200=1000. The multiplier should be at 14!!!!! (14x200=2800)

It might be caused by the cool and quiet feature.

First thing to check is if your PC IDLES on 1000Mhz...
So keep CPUZ open to the right of your screen.
On the left of the screen, do something that will make your computer work... my favorit is running Winrar benchmark test. (archiving tool, very useful) www.rarlabs.com go to download and install it. once done. Tools, Benchmark hardware test. this will make your cpu work.

When the cpu work, normally, it should go from 1000Mhz to 2800Mhz

If it does, there is no issue, it's just a feature to save electricity.

If it does not, you need to hit del or F1 or F2 (what ever it is on your acer model) right after powering the machine on in order to get to the Bios (aka Setup)

From there, you have to look around and find either a cpu option to see if your multiplier is stuck at 5... if it's 14 then it's ok.

Or you can find an option that is called cool and quiet... disable it.

Good luck

Please go back and delete 90% of those two massive posts...

And yeah, CPUs tend to downclock at idle. Run Prime95 and then check your frequency.

hey sorry to bother you but i had cpu-z up to the right and i did furmark 1280x720 burn in in windowed mode for 30 seconds and it stayed at 1000. your talk down in the left hand corner where it says my speed on cpu-z right? yeah it stayed the same

thing is like i said i dont have an option for cpu or ram timings or anything else in my bios. it was originally an acer x1200 slapped a couple aftermarket parts in it and a new case but i just dont have no options for timings in there. phoenix Tech. version R01-B0

most prebuilt from manufacturer have it locked to make sure you dont overclock it. But I didn't think they would underclock it. Who knows? Anyway, did you check for virus, adware or malware?

do as they say
use cpuz and use a program that uses a heavy load and look
at cpuz and see wehat your freq and multiplier/fsb is

i just used furmark for 60 sec or 1 min at 1280x720 windowed mode and had cpu-z up on the right stayed the same 5x multiplier 200 fsb=1000mhz need to get that multiplier up tp 14x. by the way my hyper transport is 1000 also and stayed same threw furmark

Furmark... stresses graphics cards. Granted, the CPU should show some usage, but you should run Prime 95 instead.

Also download Real Temp, because personally I've found CPUZ can sort of... lag... on showing the CPU speed. Real Temp is a lot more responsive.

how do i use prime 95 or how exactly does it work? is there a way i can watch to see if it goes up to 2800mhz . please my whole question here was how do i change the multiplier its stuck on five and i dont have a cpu fsb multiplier or d-ram timings in my bios version R01-B0 from phoenix

I can't find anything useful on that motherboard, but did you upgrade the CPU yourself by any chance?

no it come pre installed i ripped out the insides of an acer x1200 replaced the power supply threw in evga gts 450 with performance boost in a new case. i'm not an overclocker at all. cant figure out why thats stuck on x5 mutiplier instead of x14 like it should be to make the 2800mhz

You might want to simply try contacting Acer support.

But as a last effort... Prime95 you just want to run a stress test. When it opens up you have 3 options, it won't matter which one for this purpose. Watch CPUZ but also you should try downloading Real Temp because, like I said, it's more responsive to CPU speed/multiplier changes.

ok ran prime 95 for 2 minutes cpu cores never moved off of 1000mhz neither did the multiplier it stayed at 5. what options do i have in a bios that doesn't have options visible to change multiplier from 5 to 14 supposed to be running at 2.8ghz it just not its running at 1000 and a 5x multiplier

bios version: phoenix R01-B0
MOBO: WMCP78M
CPU: ATHLON 64 X2 5400+ 2.8GHZ

so basically my bus speed is 200 and it only multiplying it by 5 for 1000 core speed. when it should be multiplying it by 14 for a total of 2800 but my bios has nowhere to change that

Yeah, unless you accidentally changed something in the BIOS you probably will have to contact Acer about it. Pre built PCs like this aren't open to tinkering so there's not really much we can do for you.

OK you might want to check for virus and malware after that run prime 95 stress test and open up cpuz watch the CPU output if it doesn't climb end the test, post results here also might want to check the power options in windows OS don't know for sure but if the computer is running in low power mode it affects performance. did this problem start when you put the new psu in?

so you guys cant find no specs on that bios or system? neither could i. is there other fancy terms possibly in bios for the cpu and bus multiplier and stuff

does your motherboard support the wattage of yor processor, i recently upgraded to a quad core that runs at 3.5ghz

and when i installed it, it ran at 800mhz. turns out my motherboard only supported 95w cpu's
is your power supply enough to run the processor if not it will run at below speed

secondly if your cpu gets too hot it might reduce the speed,

if mine go's over 70 which is used to do due to a heating problem it reduced itself down to 800mhz allthough it only did that till it went back below 70.

i figured out what it was. some member on here on one of my other post said something. he was like check your power settings in windows so i did my processor was set at maxium power save. i switched it to maximum performance and it switched to 2800 core clock 14x multiplier. i was like wow all that for that
