Hello, I've recently decided to try some overclocking fun for the first time. my system is as follows:<br><br>
Lian Li PCV1100 Well ventialted (look me a while though)...<br>
Asus A8V-E SE Socket 939, Bios 1010 (latest)<br>
AMD Athlon 64 4000+ 1mb 2.4 ghz (Latest model, ADA4000DAA5BN) using Zalman 9500 LED with the fanmate controller set somewhere in the middle as of right now)<br>
2x512 PC3200 KingStone HyperX<br>
Evga 7900 GT KO RoHS (default clocked to 500/750 over stock) this uses a stock cooler, and will stay that way until I decide to use their step-up program for a G80 part.....)<br>
ViewSonic VP211b 21.3 inch LCD (doesnt matter, but bling bling)<br>
Slackware 10.2 runnign Dropline Gnome...<br>
uhh...500 gig hitachi, etc.<br><br>
Damn, Ocing is fun huh? Anways, I found a quide here...<br><br><a href="http://www.hardwaresecrets.com/article/102/1" target="_blank">http://www.hardwaresecrets.com/article/102/1</a><br><br>
It seemed to be a recent, well written guide. It started off by suggesting that you lock the PCI and PCI-E frequencys, and I was able to do that. Next I fiqured I'd then change the base clock to get a faster running CPU, and I am currently running on a ~200Mhz overclock. I haven't run any tests with Prime95, as I haven't installed them on my windows parition yet, however I fiqure I'll come to a decision tonight about general stability with some serious friday night gaming on my main Linux parition that I use 99.4 percent of the time. Regardless, I'd love to go further, but first I have some general overclocking questions, that should help me now, and when I **** around with my GPU later.<br><br>
1. Is it true that people increase the voltage just to solve stability problems which prevent them from reaching higher freqs?<br><br>
2. Generally, do you only increase the heat when you pump up that voltage?<br><br>
With this 200Mhz overclock (without a voltage change, as I'll explain later with the bios options, or lack thereof) I haven't really noticed any considerable rises in tempature. I forget what it was when I was defaultly clocked, but as far as right now, I'm running at 34 or 35 after being idled for a time, and below 50 whilst I game...So that leads me to ask question 2.<br><br>
I'd like to go from 2.6 to 2.8 ghz, but as I would imagine, I'll need to increase the CPU core voltage. However, I can't really seem to find an option for it in my bios. The 4000+ runs at a variable voltage that jumps around, and from the standard voltage that seems flcutate in the middle of 1.4-1.5 which would make sense according to wikipedia's list of athlon 64 which lists it at 1.35/1.40 v. The reason why I think the voltage runs somewhere higher than that is due to one of the bios options I'm having trouble deciphering...<br><br>
"CPU VCore Offset" it's set to +100 Mv (0.1 v right?), and it can be set to +2<br>
00 Mv. Is it my understanding that these allows you to select how much the CPU's variable voltage flucuates? More importantly, would this be a useful setting for raising the voltage to achieve a higher overclock?<br><br>
The next best option I can find for changing the CPU voltage is:<br><br>
"Hammer Vid control" And is set to "StartUp". My print manual lists a **** load of voltage options, that I couldn't find in my bios (in the bios it went from 1.4 down). Here are the options listed on the PDF manual from asus.com:<br><br>
Sets the Hammer Voltage ID control. Configuration options: [Startup]<br>
[1.5625v] [1.550 v] [1.5375v] [1.525 v] [1.5125v] [1.500 v] [1.4875v]<br>
[1.475 v] [1.4625v] [1.450 v] [1.4375v] [1.425 v] [1.4125v] [1.400 v]<br>
[1.3875v] [1.375 v] [1.3625v] [1.350 v] [1.3375v] [1.325 v] [1.3125v]<br>
[1.300 v] [1.2875v] [1.275 v] [1.2625v] [1.250 v] [1.2375v] [1.225 v]<br>
[1.2125v] [1.200 v] [1.1875v] [1.175 v] [1.1625v] [1.150 v] [1.1375v]<br>
[1.125 v] [1.1125v] [1.100 v] [1.0875v] [1.075 v] [1.0625v] [1.050 v]<br>
[1.0375v] [1.025 v] [1.0125v] [1.000 v] [0.9875v] [0.975 v] [0.9625v]<br>
[0.950 v] [0.9375v] [0.925 v] [0.9125v] [0.900 v] [0.8875v] [0.875 v]<br>
[0.8625v] [0.850 v] [0.8375v] [0.825 v] [0.8125v] [0.800 v]<br><br>
However, I get [Startup] [1.4] and then down. Which leads me to believe that this settings is based on your CPU.<br><br>
Chances are this is the option I'm looking for. If someone could help me deciper the name that would be great too.<br><br>
Heres my theory, and this is where I'd defintaly need someone with a A8V-E to help me out... do change the voltage I'd need to tweak the hammer vid below 1.4 and then increase the VCore offset to 200 mv. This doesnt seem like I can have much control in the sens that the highest voltage I could go is 1.6.<br><br>
But then again, I'm a newbie so I really don't know whats a high or low voltage increase. Like is an increase of say.. 0.3 volts a BIG increase or what? Also assuming I can tweak the voltage this way, any tips on safety when ****ing with the voltage?<br><br>
With hammervid at [startup] I moved the VCORE offset to 200mv and booted into linux, and I automatically noticed an increase up to 41 (if my short term memory (havent _ _ _ _ _ in a while so it should be fine) serves me right...) I didnt do much tests, and then immediatly jumped into the bios, and uped the base clock to around 230, to get that 2.8 (I know I know increases like that are NOT the way to test...) and my box refused to boot. Busted my ass and jumped the CMOS...reset everything and went to this forum...<br><br>
Help with the above would be very appreicated. Regardless, I'd also like some information about memory. As of right now, is my memory overclocked? Any considerations about memory?<br><br>
Also the above guide is telling me I should reduce the multiplier for the HyperTransport. As of right now (at 2.6ghz=217 baseclock) CPUZ reports me (as much I quessed) at a HT of ~1080. The guide recommends reducing the HT mulitplier at certain baseclocks so the HT doesnt get too high, which is understandable, however I can't seem to find any option like that, other than LDT bus Frequency, which has Auto, 1ghz 800 mhz,600mhz,400mhz and 200mhz) If its kinda like the PCI/PCIe options to 'lock' the frequency I would think that would be kickass in terms of not having to worry about that. IIRC I might have set it to 1ghz when I had to redo my bios options. I'll get back right after posting, with a reboot into windows; I think CPUz can tell me what thats running at...<br><br>
(.)(.)<br><br>
This is a long post, but then again I fiqure more information is good. I also plan to try and have all my questions answered about just about all my Overclocking learning (other than GPU stuff whcih will happen later...) which means Ill be relying on the phenominal expertise of all you fine forum patrons. I mean, cmon, give yourself a hand. Its people like you who have forged the enthusiast desktop segment of the market, COMPELTLY SHIRKING those money grubbing 'workstation people' who sell the same ****ing tech for triple the price! You still going! Your still strong! YOU'RE GREAT! Beearrgh!<br><br>
Thank you very very much for any comments or assistance.<br>

nope, HT Link still running at 1080 ish

and I dare say 200 mhz without a voltage change is causing games to malfunction and crash.

However, I found out that if you set the LDT Bus Frequency to 800 Mhz, the boosts to the baseclock will then add more mhz to the LDT starting at 800, instaed of 1000, coooool<br />
<br />
I also set my ram to 166 instead of 200, and brought **** back up to 2.6 ghz on the cpu, lets see how stuff works now...

Keep your HT link at or below 1000. You have to set it to 800 indeed, and if you pass 250 FSB you have to set it to 600. You also set a memory divider which was needed. Your cpu can probably run 2.6ghz on stock voltage, and 3.0ghz with some voltage increase.

In my motherboard I can't set the divider... Ill just have to lower it if Im in danger of going over 1ghz. So, I can make 3.0 huh? 2.8 should be easy. Whats the rule of them for choosing the right voltage for your target base clock? Also, can you possibly help me fiqure out how to modify the voltage on this crazy mobo? There is no easy option like that, as mentioned above, theres "Hammer Vid Control" and CPU Vcor Offset that seem to be the related options.

Yeah yeah yeah....ohh.ohh.ohh.yes. After taking control of the HTT/LDT freq and the DDR freq I see to be getting a stable system...

1080 is the thresh hold for most MBs HTT (LDT) speed. You might wnat to try to drop the multiplyer down!<br>
Don't be concerned with the loss of speed there, it's irrelvant.<br><br>
Unsure what is the issue on the voltage FID thing, perhaps there is a MB revision issue there where the manual covers more than 1 MB version.<br><br>
BTW, you may want to flash back to 1009, I recall the latest BIOS may have eliminated some BIOS functions necessary to sucessful OCing.

Oh yeah, I didnt raelly think having a lower HTT (which will get faster than 800 mhz as the base clock increases, whould be much of a problem.<br><br>
Any tips on working with the a8v-e se and general voltage info would be nice, also whats the 1t/2t memory option?

The CPC or Command is a RAM to MB timing thing, not an actuall RAM timing spec. 1T is fastest, 2T can promote stability when the RAM is pushed to it's peak stable speed. 2T will effect the performance about 3-5% in real world apps, in benchmarks that's a different and very skewed story so don't be concerned with the 2T effect in benchmarks.

So what do you recommend for the memoy setting? Also that motherboard info doesn't help as you can just manually tell it what voltage you want, whereas in mine I have two confusing options.

Memory timings can be a pain. The guide on how to find there highest stable speed should be helpful.<br><br>
What are the default timings of the RAM. A CPU-Z screen shot of the SPD tab would help.

Hmm, I looked intyo the 1t/2t option and it appears increasing the clock of the ram would be a better idea. Do people change their memory timing options? Or is it also advisable to keep those stable to get a better clock? Anyways, of higher importance is the crazy voltage settings in the asus a8v-e se.

Timings...<br>
Relaxing... to aquire higher speeds along with voltage increases.<br>
Tighter timings are good, but relaxing them and compensating with higher speeds somewhat ballances it out.

heres a ****load of info from cpuz<br />
Ill have to look for into how memory timings work and stuff, but ill post a picture here for any quick comments. I'm running in whatever the bios has by default. I had to change the ram setting to manual to get in there to change the ddr frequency, so I may very well be running my ram timings slower than what I could be (its hyperx memory designed for this kinda stuff I hear), in a second Illl fiqure out what model im using (matched pair) and see where Im at.<br />
<br />
<br />
hammer vid? vcore offset? anybody?<br />
<br />

cpuz isnt helping me find the exact part number, ajnd there are two products on kingstons website for their 1 gig kingsont hyper x pc3200 matche pairs. Any help/tips on finding out what I have? (Ive been using this patched pair for along time, as you can see, over a previous socket 754 a64, and maybe even my older athlon xp system (crazy old school)

Being your at 173 MHz on your RAM with those timings you have a bunch of head room for CPU OCing.<br />
Considering that and you may not have anymore head room on the CPU OC, you may either be able to either decrease your divider or tighten your timings a bit.

Oh I'm defintaly not done with overclocking my cpu, I dont quite have the patience for prime95 at just a 200 mhz overclock, so I quess Ill just shove it up to 2.8 ghz and see whats the from there.<br />
<br />
I always kinda fiqured dropping your ram down to 166 and then pumping up the baseclock to get it back up around 200 would be a good starting point for any newbie overclocker. At least with athlon 64 overclocking.
