Why only 1530??

[train22]

You can see my sys in the sig, my cooling is good I get 41C Idle and 44 full load but it only lets me get to 1532 with the highest FSB @ 153[x10], will it help if I raise my DDR Core Voltage whatever that refers to? [in bios] I can also raise my CPU Vcore but that will only help me get more out of the multiplier I want to max my FSB first, any1 know what I shold do?

By the way I don't think this matter sience my comp does well enough on temps (It reads 44C max load on MBM5 for the CPU) but my room temp is 79F which is a little over 26C.

So what shall I do???

1500 pretty much seems to be where the current generation of Athlons (AXIA, AYJHA) max out. I just got a 1.33 AYJHA and it runs stable at 1500 but is unstable at 1575 MHz. I have not checked the in-between speeds and don't intend to because 150 MHz is the fastest FSB my memory will work at, and I don't care to lower the FSB for a measly 5-10 extra MHz ;)

The really amazing thing is that the chip runs fine at 1500 with default voltage (100% rock solid), but will not even boot into windows at 1575 regardless of how much juice I give it. Since voltage increases are no longer helping out, I can only determine that 1500 is pretty much the max my chip can handle.

My experiences were the same with an AXIA 1 GHz. It runs fine at 1425 with default voltage, and I could get it to run at 1475 by maxxing the voltage out (I don't believe that it could run at 1500). But considering how hot these chips already run, I figured 50 extra MHz was not worth giving the chip 2.10 volts ;)

Anyway, don't be too disappointed with 1500. I don't think many people will get far beyond that with current chips without super cooling. Of course it's also possible we both just got dud chips.

that cant be true, most 1.4 AJ-Y's can hit 1.6 and above, I don't know why I can't, probably because of my memory but what I am asking is if I raise my DDR voltage will that help???

[train22]

I've been running Prime95 for an hour now and CPU temps stay rock solid at 43C yet I still can't raise my FSB higher than 155 (it crashes sometimes @ 155) I haven't tried the clock mult yet but I really want to know if 153 is what I will get outa 2.65volts DDR?

[Basher]

Could be because of the PC 2100 memory, maybe pc 2400 would be able to hit higher speeds.

[train22]

no if it would be somthing it would be that it is CAS 2.5 instad of 2, I should have gotten 2 but that's ok, do you know if adding to teh DDR Vcore is dangerous? I'ts currently at 2.75 it allowed me to get to 155 stable but is it dangerous?? Why don't I just max it? CPU temps still seem ok wont they?

[Basher]

I'm not upto speed on ddr yet but there were some nice discussions on the seti page here (http://forums.overclockers.ws/vb/showthread.php?s=&threadid=31227) is a link to one of them. We have a few hard core oc'ers there who may be able to help you out over there.

As long as you feel your mem and it doesn't seem to be getting too hot, I think it's a relatively safe voltage.

I also think that the memory might be maxed at 155. Crucial is good stuff, but only the PC 2400 is meant to go much higher than 150 anyhow.

Another problem could be the CPU core voltage. Try jacking it up a notch or two and see if that helps.

Good luck

The CPU database can be somewhat misleading...I think the main problem is people only post to the database when they get a good overclock (sort of for bragging rights), so it's always going to be a little "overly optimistic".

Anyway, I still wouldn't be too concerned. 1600 MHz is not going to be THAT much faster than 1500. And I really doubt you are being limited by anything other than your CPU.

I guess if you REALLY NEED 1600 you had best go buy a new chip and put your current one in a second system or auction it off on Ebay.

well im still tinkering around but this is what ive gut 1600 41c idle
? full load.... x12 multiplier 133 fsb and 1.85 vcore.....

runs 3-dmark 2001 without freezing and runs games fine havent really tested it well enough to say its completely stable though.. look at my specs

o ya and not to intrude on your post but seeing we where talking about temps to any idea why mbm gives me temps of 30c (which i know is wrong) and abits pc health is like 41c???:confused:

Yeah, I can only get about 1525 stable out of mine also.I was hoping to get alot higher.I've been having alot of other problems with hardware though so I haven't been able to mess with it much until I can get all my RMA's back and get my comp running smooth first.My biggest problem is the heat it generates I don't want to go any higher because I'm at 54c now.
