Help Overclocking. No Success

[DJSfurry]

i recently bought a 3200+ 90nm core and was hoping to have it run at 2.5Ghz however i can reach 2.15 being the most stable. anything over 2.2 and windows wont load up past the laoding screen, comp just resets. i have patriot 2.5/3/3 ram and i dont know if this is the problem. at 2.1 my cpu idles at 30 celcius and under load rarely goes past 37. any ideas on what could be causing my computer to reboot? im running the cpu on a asus A8V deluxe mobo. Thx in advance for any advice

What kind of RAM ya got? I have same mobo w/ 3500+ 90nm core and could not get my pc stable with oc's till I up-ped my mem voltage to 2.8 but b4 you do this find out what your RAM is rated for! You can fry it! Your temps are great and you have much room for improvement if ya got GOOD RAM! Whats your command rate? Whats your HTT at? What are your timings? Need some more info from ya

Also make sure the HTT is turned from 5x to 4x

There is no 3x/4x/5x on the A8V mobo's unfortunately ASUS has made manual oc'ing confusing to the "layman" oc'er. This is also true for their RAM ratio settings. On the A8V deluxe 2:1 (DDR 400) is 1:1 on almost ALL other mobo's. Confusing honh? Actually unless you are oc'ing with more than a 210 FSB your HTT should be set at 5x which on the A8V mobo is 1000MHz speed. 210FSB with the 2:1 mem setting will give you 1050MHz HTT which is safe on this board.

Doesnt pertain to your particular mobo but is informative reading none-the-less

im not sure how to adjust the HTT multiplier on my board. havent seen any settings. the im not sure what the exact ram is. but its the PDP Patriot Signature Line DDR and on CPU-Z shows CL of 2.5, Ras to Cas at 3 Ras precharge at 3 Tras at 8, TRC at 12 and DRAM idle timer at 16. i dont know how much Voltage i can run through this ram. It says my HTT is at 210Mhz. i might also add that im fairly new to this overclocking thing so im not familiar with all the Ram timings and all of that. i have most of that stuff set on auto on my board.

 

[JBDan]

Is all good bro you will get it straight. Dats wut these forums are here for ask all ya want!

 

[DJSfurry]

just read your reply. are you saying i should change the divider to 2:1 and see how that works? i had some stability issues with this computer in the past few days. while play Source or HL2 i experienced glitchiness and all but i reinstalled the drivers and reduced AGP speed to 4x which has since run fine.

Read my reply? Am I missin something? The divider at 2:1 on this mobo is not a divider at all! AGP should be set to 8x not 4x. Take it slow. Read the linky I posted it should enlighten you somewhat and if not send me a PM will be glad to help. I am very familiar with this board and its potential

 

[DJSfurry]

alright i just set the divider at 2:1 and AGP back to 8x. i will try running source now and see if the system reboots.

 

[DJSfurry]

alright. seems that the 2:1 ratio combined with the 8x agp speed works perfectly fine. 14 rounds of cs. no glitching no freezes. thanks. i was looking at the HTT Speeds i can choose from in the BIOS 1000, 800, 600, 400 etc. does asus mean by 1000 mhz htt it refers to the 200x5 and the 800 speed is suggesting a 4x multiplier at the stock 200mhz proccessor speeds?

You are correct! ASUS is really making things difficult and it tee's me off a little. Will go with Epox/Abit for me next board!

 

[DJSfurry]

gah. confusing stuff. thanks for your help. i do have problems though getting even a 220HTT to load up windows. ive tried that with both the 1000mhz HT and a 800mhz HT but both times the computer cant load into windows. my vcore is 1.425. is this enough? or could it be too low for the speeds im trying to get?

CPU voltage is good. Could go to 1.450. What is your mem voltage at? Only have 3 options with this mobo 2.6/2.7/2.8 I use 2.8 for my corsair xl 3200 2-2-2-5 which is rated @ 2.75 volt. My mem voltage is @ 2.8 and this made all the diff in the world for my stability. I am running 220FSB x 11 multiplier = 2.42GHz with 2.8 mem voltage/ 2.5-3-3-6 timings/ agp-pci lock ON / HTT 1000 or 5x / mem mode on LIMIT 2:1 DDR 400 / 2T command rate disabled / 1.6 agp voltage / My guess is that your prob is related to your RAM. Read that link I posted earlier closely and you will see. At 220FSB and your HTT set @ 1000 >will result in a 1100 HTT and DDR440 which works fine on my pc prime 95 stable for hours, but each system varies. Many say that when HTT gets above 1000 you can become unstable. I have not found this until I go above 1120HTT.

If you've got him set at 2:1 for the memory divider (DDR400), then his memory is running synch with the HTT, which he presently has at 220. His generic PC3200 ram is what is stuck at 220, in all likelihood. He's going to have to go with a different divider. I'm not familiar with that board's divider options, but you're going to need to find a memory divider that will let your memory run slower than your HTT. I'm used to Epox boards, where they display my memory speed as a percentage of my FSB.

Basically, it seems like the overclocking limit of your RAM is ~220, so you're going to have to keep it under that to be able to continue overclocking your CPU/pushing your HTT. You may want to set your board to an 800mhz HT instead of 1000mhz setting at this point, if you make it further, because if you're at 220 HTT, that's 220 x 5 = 1100mhz. While your board may be able to do this safely, there is no guarantee. Go from there.

i have my mem voltage at auto but just tried with agp at 1.6 and mem at 2.7. still unstable but i dont want to push my memory to 2.8 yet. i will look for other users and see if they have run this memory that high. is there a large chance that running memory at 2.8 could cause it to fail? gah. my friend will be bringing his ram over here for me to try. i guess the only thing i can do IS run the ram up to 2.8 and see how. thanks again for all your advice!

All so confusing on this ASUS board. 2:1 is NOT a divider for this mobo. Just pretend when someone speaks of an ASUS A8V Deluxe and 2:1 it really MEANS 1:1 for the RAM. I hope they fix this in an upcoming BIOS! But you are correct in saying "in-sync" avalon. Your prob DJS lies in your RAM and it is not necesarily a prob just holding you back from oc'ing the way you want. What is your RAM rated @ ? pc3200? 2.6 volts?

 

[DJSfurry]

PC 3200 CL2.5 im not sure what the voltage is at.

 

[DJSfurry]

Hey guys! i was reading around the forums just then and saw a few other people running 2.8v through their ram and so i said f-it. so i go into bios and set the ram at 2.8 and set the htt to 220 and voila! im running 2.2 ghz haha so it really was the ram holding me back thanks so much. i better test to see if its stable then take it up to 2.3

 

[JBDan]

With the 2:1 limit option set on your mem 220 plus or minus 5 MHz should be all you can get. If you are really into oc'ing your machine than a divider will be needed for you mem, but this is NOT the optimum way to run your RAM. Go to your RAM website and see what it is rated at as far as voltage. Increasing the voltage to 2.8 will increase stability, but make sure the RAM you have is capable of this. I'm sure it would be fine but make sure plz. Unfortunately I am in the same boat as you and wish I had purchased DDR500 mem. I had no idea these winchester cores would oc so well! My mem is holding me back as well. With a divider set on my mem i cannot pass prime for crap so I will save some $ and get pc 4000 or 4400 soon The 2:1 ratio (on A8V ) or 1:1 on most other mobos IS the optimum way to run your RAM on an AMD64 machine. So if you can run 210FSB x 10 mult @ 1T command @ 2.5-3-3-6/10 and 1000HTT than your doing good and STABLE. Did you read that link?

LOL i told ya! niSE

 

[DJSfurry]

haha yes i have read the link, and i actually had read it a few weeks ago too, when doing some research. unfortunately it seems my luck has run out. i tried 2.3 with a vcore of 1.5 and it wouldent start windows. so i lowered the HTT to 800mhz hoping that would work but it didnt. right now i have 2.25 ghz running on here and seems stable so far, with the HTT up to 1000 again. i lowered the vcore to 1.45 for this. would running too high a vcore without enough HTT result in instability?

Use a memory divider so that your memory runs asynchronous from the HTT, at a lower speed than it. That way you will be able to overclock your CPU to the limits of the CPU, and not the weaker limits of your RAM. You don't need expensive memory. If you play your cards right, and use the right balance between memory dividers and HTT speeds, you WILL reach an optimum level for both, as well as get about the best overclock you can get. Trying to go for a 1:1 (or 2:1 as your board calls it) overclock on generic PC3200 will not get you any farther.

 

[DJSfurry]

Thx Avalon. your advice worked and took me from 2.2 up to 2.4 so far. i chose a 5:3 divider which i dont know what it really means on this board since its kinda messed up but either way at 2.4 i have the HTT using a multiplier of 4 getting me a 960mhz HTT which i presume is safe. with this divider, ram runs at 200 mhz exactly which is what its rated at, so thats good timings on cpu-z read 2.5 3 3 7. what i do notice with the higher CPU speeds is quite peculiar though, i get lower FPS in the source stress test. any reasons for this?

The divider is one reason and the other is your FSB speed. The divider on your RAM/FSB runs your RAM in an asynchronous state which is not the optimum way to run it. Your FSB only being 40MHz lower than the stock 1000MHz is not that much granted it IS slower. I have found that oc'ing my cpu so high that I need a RAM divider only gives me better bench scores (everest, sandra, etc..) Real world performance (for me its games) Im best with the 2:1 setting 220FSB 11 mult 2.5-3-3-6 HTT 1000. For the best allaround performance (games, apps, benches) higher speed rated mem is the way to go ( ie. pc3700/4000/4400 ) so you can keep that 2:1 ratio and just increase that FSB. I have also read many reviews on having the highest mult possible is best.

 

[DJSfurry]

yeah. damn ive been reading about that gskill ram. OMGWTF MUST BUYBUYBUY!!!!111oneone but i dont ill be getting that anytime soon as i just bought some of this patriot ram about a month n a half ago. gah. one day... one day.... maybe if i fry it while overclocking... hey do you have an opinion on whats the best kind of divider to use on that board that doesnt slow down ram clock speeds too much?
