Hello All,

Good Day! Hope all is well.

I have an AMD Athlon x3 455 processor got unlocked to AMD Phenom x4 B55 processor. When I ran prime95, no errors and BSOD however i just noticed that it's running @ 800MHz (full load) with a multiplier of JUST "4" an checked PC PROBE II: Vcore says 1.12v. Question is, is this normal? running @ 800MHz with a vcore of 1.12. From what I know, if it's in full load, should it be 3300MHz on all cores? Please help! Thanks in advance and appreciate all your responses.
 
AMD Phenom II x4 B55 - 3.3Ghz

it goes something like this:

freq #0: 800MHz (200 x 4) - full load
freq #1: 800MHz (200 x 4) - full load
freq #2: 800MHz (200 x 4) - full load
freq #3: 800MHz (200 x 4) - full load

this is when running prime95..Vcore says: 1.12v

is this correct? 800MHz, it should go 3300MHz at full load right? i'm under the impression that the Vcore is very low. Please help. Thanks!
 
Man, we've been over this, lol. No, it's not normal, as we've talked about. It's the faulty 4th Core that's causing it and there's almost definitely nothing you can do to fix it. Just keep it as an X3, since we KNOW it works right that way.
 
mobo doesnt support the Phenom X4

*edit* thats what normally happens when the mobo doesnt support. An unstable core wouldnt cause it all to throttle to 800 it would just cause stability issues or refuse to boot if extreme, check your mobo support list see if it handles X4 phenoms of that core type
 
He should check his bios version then the X4 multi is what happens when the CPU isn't supported (usually 125W CPU's on a 95W max board)

Never seen or heard of that issue being down to dodgy cores that should either refuse to boot or just become unstable when booted not throttle the 3 good ones.
 


THAT is actually a very good point that totally slipped my mind, for some reason (bad tech support person. BAD! LOL). Anyway, yes kamotekid, try updating your BIOS.
 
Guys,

Thanks for all the responses. @djdecibeL, sorry I can't get over it. I tried reading all posts online for the past 2 weeks and haven't heard any issues with the core speed when unlocked. I'm planning to revert it back to 4 cores and see if the Vcore changes. coz what happened was, when I relock the core, Vcore automatically change its voltage. will it do harm to my system? changing back and forth - i mean unlocking and relocking cores in the BIOS? BIOS update? that sounds good but I just bought it a couple of weeks ago so i presume that what i have on the cd is not way too far from the updated BIOS. Thanks Guys!
 
M5A88-V EVO BIOS 0707
Fix the issue that the size may be incorrect when build RAID with 3TB HDD.
1. Backup all the data in the RAID partition before updating the BIOS.

-does it mean that I have to back all files that I have in the C drive before doing it? sorry not familiar with RAID processes
 
No, going back and forth from locked core to unlocked core shouldn't damage anything.

The thing with the BIOS is that it may not have shipped with the newest BIOS, no matter how recently you bought it. There wouldn't be an updated one on the CD anyway. That's something you have to download from the support site.

What you saw with the the 3 cores working is the way it should be with 4 cores too, if everything is working correctly. Go here http://www.asus.com/Motherboards/AMD_AM3Plus/M5A88V_EVO/#download and download BIOS version 1202.

And you don't have a RAID setup, I'm guessing, so that shouldn't apply to you.
 
One thing I should mention is that you may have to download and use the BIOS update utility too, unless that motherboard allows BIOS updates through the BIOS itself (like my P8Z68-V LE can do). If it does, you can just put the BIOS on a USB drive and go into the BIOS to do it from there.
 
thank you so much for the support and help guys! no wonder this site was recommended a friend of mine because you guys are great! anyway, i've downloaded the BIOS already using "GLOBAL" since "global DLM" is not possible here because of restrictions :fou:

-i'll try to do the unlocking again and see it works the same with the 3cores as far as core speed is concern (hope it won't damage my mobo and cpu and i can still revert it back to 3cores in the event that i unlock it with the 4th core

-i agree with you, from what i can recall with the BIOS version, it's not up to date, i received the CD with the drivers and utilities. i'll double check the version of the BIOS if there's need for it to be updated but am 99.99% sure that it's around ver 0707. i also installed the BIOS update interface wherein i can navigate the page of what type of update i want to do but i guess since i don't have internet at home, i'll save it to my flash drive then run it at home. regarding RAID, I also installed it, which came with the CD and when I installed the OS (win7 64bit), it's just a clean install, no special partition, just C drive so basing it to your post, it's just click and run with backing up my files in my C drive. just wondering if it affects my files since i installed the RAID options in the "utilities" option in the CD
 
You only have one HDD with one partition, right? If you do, RAID wouldn't even be an issue, enabled/installed or not. RAID is for multiple drives. You're most likely actually using AHCI mode.

In other words, don't worry about backing anything up. If the update goes wrong, data loss won't be why.
 
yup you're dead right..i only got 1 HDD, 1 partition in AHCI mode so thanks for confirming that my drive won't be affected if I'm going to flash the BIOS. At least, no worries about backing up the files first.

about the BIOS update utility, i don't have internet at home so what I'm wanting to do is save it to my flash drive. I'm just not sure if in the BIOS update utility (usually this can be accessed thru windows right? just to make sure we're on the same page) there's a way i can upload the files from the USB so i can flash the BIOS.

is is possible to just access the file from the USB drive and run it? or is it imperative for me to use BIOS update utility?
 
If you have to use the update utility, it'll be through DOS after making the USB drive bootable. But I just checked, and that board DOES have EZ-Flash (what I was talking about earlier), so all you need to do is put the BIOS .ROM file on the USB drive and then boot into the BIOS to do it from there. I don't know if that board has a UEFI BIOS (Graphical, instead of just text) or not, but in my BIOS, which IS UEFI, it under the "Tool" section in Advanced Mode.
 
wow! nose bleed..i will read it one more time. LOL!

yup..i have EZ-Flash but no idea how to use it. what's the easiest way to do it? my only option is just thru USB drive since i don't have net at home 🙁
 
A USB drive is how you HAVE to do it, so you're good there. :) I've never used EZ-Flash on my own Asus board, so I really don't know exactly how it works, but, from what I gather, you just go into EZ-Flash in the BIOS and select the BIOS .ROM file (will be named M5A88-V-EVO-ASUS-1202.ROM) on the USB drive (and then hit enter or whatever it says to update it).
 
thanks! that's way better and easier than the previous post. LOL! sorry i can't comprehend the instructions from the previous post, so techie with the terminologies. LOL!

from what i can recall, i believe i saw EZ flash in one of the tabs there before "EXIT" BIOS.ROM file - is this regardless if you've downloaded it via "GLOBAL (DLM" or "GLOBAL"?
 
thanks sir. i was able to unzipped the file and indeed that's the same name of the file listed above..i have an idea now how to do it. should i empty the USB drive and just have the .ROM file as the only file there?
 
It doesn't have to be the only file on there, I guess, no. Just make sure it's in the root directory and not in a folder. You might be able to get to a folder it's in, but it'll be easier if it's not in a folder, just there in the root directory (ie. *:\M5A88-V-EVO-ASUS-1202.ROM. The * is the drive letter of course. May be anything A-Z, but it will probably be C).
 
will it be easier if i'll just remove all the files i have on there to avoid confusion since i only got 2 word files here and just leave that drive store that file (.ROM file)?
