2500+ Detected as 1100+

[TalentX]

AMD 2500+ (Stock HSF)
512MB Kinston HyperX Dual Channel PC3200
400Watt PS
30GB Maxtor HDD
25GB Western Digital HDD
Geforce4 MX420 (I know it's ancient )
Gigabyte GA-7N400 Pro2 Mobo (Nforce2 Chipset)
ThermalTake Xaser3 Skull Series Tower

During boot CPU is detected as running @ 1100Mhz. This obviously isn't correct for a 2500+. Mutliplier was set at 11.5. FSB was FIXED in the BIOS @ 200Mhz but CPU still ran @ 1100Mhz.

Altered Jumpers so as to alter FSB ratio and Machine would boot and freeze in the BIOS screen, upon resetting was greeted by a black screen, with no activity save for a QUICKLY rising temperature of the CPU.

Looking to overclock this CPU to the fabled 3200+ speeds, and need a hand, thx.

Suggestions?

Don't post the same problem in multiple forums.

Buzzing Mobo?

Well I was trying to be proper. The First Thread was in motherboards, which was what it regarded. This is about my CPU, NOT my motherboard. There are different forums for a reason correct? I would think you'd want people to post in the appropriate place, Sorry I didn't know you wanted threads to change into topics unrelated to a forums Title.

(Don't mean to sound condescending, I really don't, I like these forums and the people that use them are extremly helpful. I was TRYING to follow some basic etiquette.)

Actually, multiplier settings for the 2500+ should NOT be 11.5, rather it needs to be 11. When I try setting the multi on my 2800+ Barton higher than stock, then the CPU is defaulted back to some low number, think it's 1250MHz. All things being equal, you need to check to make sure you're using the stock multi of 11.

Also, you may want to double check the mobo to make sure the CMOS clear jumper is in the off position. Check your mobo manual for the proper jumper configuration for the CMOS clear function.

If you want to overclock to 3200+ speeds, then stick the multi back to 11, and set the FSB to 200. This will give you 2200 REAL MHz, the speed of the 3200+.

Also, keep in mind that all chips are not created equal, and that you MAY not be able to get 3200+ speeds out of that particular chip. First, make sure the CPU is correctly recognized at stock speeds, then worry about tinkering with it. Raising the FSB incrementally may help with stabilizing your overclock. Then, you get to figure out where and when you will need to apply additional core voltage, and you're going to want to make sure the temps don't get too high, ESPECIALLY since you are using the STOCK HSF {I hope you at least applied thermal compound to the HSF, and didn't just go with the pad they supply with them. If not, then you're better off grabbing up some AS3 or better and cleaning off the pad).

So try running it as a 2500+ first. Then let us know how that works out, and up the FSB SLOWLY.

You need to set the clock switch and clock ratio dip swithes on the mobo. Refer to the charts on page 14 of the manual.

clock ratio location


166 mhz FSB is the "stock" speed. Try that for a while, before going higher. See how the temps are.

GOD I love these forums. Good stuff Dallas, I have it recognized as a 2600+ Atm. Buying a Thermaltake Volcano 12 in a few weeks (With compound Nanotherm or arctic silver3? )

Multiplier of 11
FSB of 356Mhz 48c Idle

I oc'ed my 2000+ and now its recognized as a 2600+ yay! 166 mhz fsb all the way!
