Cant get fsb higher that 215??

[Hellotalkie]

When ever i have oc up to 215 and up the computer either wont boot or system hangs at setup.Also the bios freezez.


amd 64 3200+

2gb ram
gigabyte sli pro

Did you use a memory divider to keep your ram from being overclocked? Did you lower the HTT multiplier to 4x? Do you have an adiquate power supply?

 

[mindwreck]

check pretty much everything stevty said. What kind of ram do you have, t seems your ram is being overclocked too high

 

[KBTuning]

use the HTT multiplier. and make sure you gots a beefy PSU

 

[theMan]

reduce the ldt (ht multi) make sure you have a pci lock set to 33mhz.

Need more info to make a real effort at this. I'm running a 3200+ on a MSI Neo2 Plat, 2-512MB Sticks of Ocz PC3200 Plat Rev 2 (2.5-3-3-10 1T @ 240Mhz) HTT at 3, vcore @ 1.52 and the FSB is 300.

As such, I would make sure your HTT is at 2 or 3, drop your memory to the 100 divider to take it out of the equation, drop the multi down to 5 or so and keep the cpu out of the issue also, and boot up at 240 or so to get into windows. From here, you can play with ClockGen and push the FSB up at 5Mhz steps till you reach the end...just my thoughts.

What kind of RAM do you have?

You need to have a performance RAM like Corsair or OCZ, need OC Skills like: voltage adjustment, divider utilisation...and then your system will boot properly.

 

[Hellotalkie]

well someone told me it was my mb since he cant oc hihger. I have corsair value selct ram and is the htt thing ht frequency?

 

[diapickle]

corsair values don't OC very far, try dropping the divider

 

[Lord Banshee]

my corsair values OC way more than i expected (see sig).

the Memeroy divider every one is talking about should have settings like (100,133,166,200) or (1/2, 2/3, 4/5, 1/1).

The HTT thing you refer to is has setting like so (1x, 2x, 3x, 4x, 5x) or (200, 400, 600, 800, 1000).

BTW have you read the sticky?

 

[Hellotalkie]

ok i have turned down too 100 and havent tried the multiplier. Myne is called ht frequency. I dont know if this means any thing but when i press it it comes with something like 1x 2x 3x 4x etc. I followed the direction showed in the hardforums.

 

[Hellotalkie]

also what should i set my ht thing to??

 

[theMan]

you should set it to 3x or 2x.

 

[Hellotalkie]

what about the central spread. enable or diable

 

[Hellotalkie]

And also do i have to lock the pci and how do i if i have too

 

[Hellotalkie]

will setting the htt to x1 good or bad? Ok just an update i tried overclocking with clockgen just to see if iam stable and once i hit 217 it restarts. i have the clock ratio to x5 1000. I didnt turn central spread off and i dont knw if i should. I had teh ht frequency (htt) to 2x and to 100mhz.

 

[Hellotalkie]

nobody???

 

[Unkno]

no, dont' set your htt to 1x, keep it as near as 1000 as possible, FSB x HTT = As close as 1000.

set your pci to 33mhz to lock it

 

[Hellotalkie]

no for the ram

 

[Losty]

umm if you have options that are 1x 2x 3x 4x 5x only .. keep it at 4 or 3 since you don't go past 250mhz.

If it's the ram you suspect is the problem ... put it at 100 and lower your FID (multiplier) to see what the max HTT is. Bump up the htt 5 mhz increments until it doesn't post. back it off a lil and you should be fine. It should go past 215 ... if not it might be the board.

you should try to find the max htt first. Than find out the max your cpu will go. To do this just keep your memory at 100 and the ht at 4 (3 if you go past 250) and the FID at stock and bump the the HTT until it doesn't freezes in windows... back it off a lil and then do some cpu testing to see what it is stable at.

since your memory is corsair value select ... oc this last ... so you know the board and cpu do fine... oc the memory. Most of these chips don't oc well (i have one that won't do 210 ... but some will do very well ... i have a newer one that does 250 stable with memtest for over 24hours ... depends what you have)

good luck

-losty

please feel free to correct me if i'm wrong... i just oc'd mine sucessfully a month ago ... problem was using 2 ram chips i had to change the timing command to 2T .... you should try this to... put your timing command at 2T. Info mostly thanks to Zebo's oc'ing thread.
hope i didn't get anything wrong.


edit: just read this

I have a socket 745 Sempron 2600 with a similar situation. The lame Biostar board I have won't go higher than 250FSB (there aren't any options to do anything faster in the BIOS) so I don't have any idea what the CPU itself will do, but my Corsair Value Select RAM will not boot at anything higher than 220 FSB even at CAS3 so I set the memory divider to 166 and pushed the board up to the max of 250 and everything is perfectly stable.

At this setting, the CPU is running at an even 2GHz and the RAM is running at 216/432 MHz with no problems at all. I would love to push it even higher since I'm sure the CPU can do a lot more (it's still at stock voltage and doesn't even break 38 degrees Celsius under full load with an ambient temperature of 32 Celcius - wife likes the house warm) but my boring motherboard won't let me. Hopefully your results will be better once you get the RAM running at a speed it likes.


edit: Forgot to mention that I left my HTT multiplier at 4X since the board won't go higher than 250MHz FSB so the total HTT tops out at 1000 and according to the sticky and other sources, you only need to start using lower multipliers if the HTT is going higher than 1000.
