Is anyone runnin PC133@155??

[Trap]

I'm just wonderin.Im stuck @ 150 with my Micron.Im a little bit affraid to go higher..What do u think?
Should i try and go for 155fsb?
Current settz are 3-3-3,7/9

Won't hurt anything to try. Plenty of us have run memory much higher than 150MHz. Well into the 160s and up. All of my Micron RAM will do at least 150MHz...will do more but I have failure in my PCI devices.

Hey Jon,my PCI is now @37MHz,and it will go to 38 if i set FSB to 155.Would that b too much for my IBM 60GXP,SbLive and Dlink ethernet card?

I'm running 155fsb on my kt7a raif with winbond 256 memory cas2 mem timing medium

All you can do is try. If one of them doesn't like it, you'll be the first to know.

I just finished one bench in 3DMark 2k1 and everythin went ok ...yeepeeeeeeee
But one thing that i noticed is that stupid 3D mark saw my cpu as 1.06GHz not 1.08GHz when i checked project details.Ill now order him to do 6 loops for the punishment lol lol
I'll let ya know how it went
cheers:D :D :D

whooooohooooo
It rocks stable!!!!
2 hrs of intense benchmarks and gaming unbelievable!!!
I didn't even need to increase the voltage...those cD0 933s are really amazing.I'm also pleasantly surprised with Microns RAM.I knew its good but that good..wow:cool: :D :beer:

I got my brand X ram (Xerox chips) up to 160mhz, cas2-2-2 so far. I bet it could go farther, but my CPU won't.

I'd imagine quality RAM like Micron would ge even higher! you won't hurt anything by trying, if it don't work just reboot and try it a bit slower!:D

i run my samsung at 155mhz without voltage increase and its rock solid.

When your comp crashes from an overclock, how do you know what caused it. Is it ram or CPU? How do you tell

[Monaco]

memory errors are more likely to cause reboots instead of a crash, sometimes with an error message that talks about a failure at a hex location.

Try running the Sisoft Sandra burn-in test with just the memory tester enabled- that will stress justy the memory so you can see what's up. For me, if I can run that test for 3 hours, I call it stable and crank it up some more.

[Cluster]

And if i do the same with my processor than it's should be okay to crank it too right? That's what i did, the proc was stable at 146.6, I upped it to 150 using CPU FSB, and it froze instantly. I didn't think it had anything to do with the PCI at 30MHz, cuz it's an underclock, or the temps, since it was that instant, could it be the program? Or would it be the AGP being at 75MHz, it's a GF2 Ti.

One last question: Sometimes when im running CPUFSB i get an error about it can't read the PLL, sometimes it does it, others it don't. It's kind of random. Any reason why it would do this or a fix for it. There was no help from the program or the programmer.

I run mine at 150 in a KT7A Raid cas 2, turbo, all memory settings at max. It will run at 155 but I have to bump the I/O voltage up a little to more then I care to in order to make it stable so I stay at 150. The memory is 384 meg of Mushkin rev3. In a P3 I have run as high as 166 but the P3 is easier on memory then AMD systems are and the benchmarks show it to....sad! I find that boosting memory timings has a greater effet then fsb and is more important so consider that when uping the fsb. I get DDR memory speeds out of my system after tweeking! This buys me time I don't feel a need to upgrade until the next big leap in mem tech comes along.

[Monaco]

i think CPUFSB is your problem. It is a neat program, but it doesn't always work. For me, any lind of soft-set program like that gives me an immediate crash, no matter what I do.

The fact that it sometimes can't find your PLL chip is warning enough to meit ain't gonna work right for you!:D Try just making your changes in BIOS.

Also- does your board have the 'memory at +33' option? With my board, I can run th ememory +or- 33mhz from the FSB, thislets me crank the CPU up as high as possible without even stressing the RAM. Once I've found the CPU's stop point, I crank it back to default and speed up the RAM. Then, when I start winding up the FSB again, if the system chokes before I get to my CPU's sopt point I know it is the RAM.

A little process of elimination!:D

I went to 171 222 with mine.. it´s ocz with infineon chips, 7.5ns.

my bios doesn't have any kind of overclocking, looks like im sh** outta luck, gonna have to get a new board, oh well
