Overclocking A64 3000+

Hey guys,
I got a n00b question about overclocking the A64 3000+. Should I even think about doing this with the standard HSF? I'm planning to use this machine for 2 years -- will overclocking destroy my machine before 2 years is up?
I can't be sure about my CPU temperatures right now coz I'm not 100% sure the K8N Neo Platinum temperature issues have been finalized yet, but under load, my HSF does not appear to be very hot...
Please pardon my ignorance.
Thanks in advance.

With standard HSF I wouldn't go more than 10% OC to be sure that the system will last... anyway 2200 MHz is not that bad after all

My A64 3000 @ 2.3Ghz 1:1 - Can you help me go further? :o)

Hello everyone. Just wondering if anyone can help me. I have hit a brick wall with my overclock but I hope I can push it a little bit further, since other people have started to have more success.
So far I have managed 230HT 1:1 thus reaching 2.3Ghz with my A64 3000 @ 1.6v. My ram is rated to run at 250HT max of 1.9v - so I hope I can go further.
My spec is:
MSI K8N Neo Platinum
BIOS 1.25Beta
Athlon 64 3000 Newcastle
1gig GeIL PC4000 Ram
ATI Radeon 9800 XT
I have shifted thru a lot of the threads on this forum but lack any kind of solid evidence or solutions. Also, I'm unsure as to what bios I should use. I have never had a temperature problem with my board so I'm looking for overclock stability only. I know it's a lot of trial and error, overclocking I mean, but any help would be appreciated!
Thanks for reading.

Thanks alot for your answer... If I do that, will I get the CPU with 2.3 GHz ?
Or is there one more thing to do ??
you said : Set AGP lock to 68 ... Is this in Bios under : "Adjust AGP Frequency" ?
and you said : Increase HT speed setting to 230 ... Do you mean the part which is "Adjust CPU FSB Frequency" in the Bios ?
Is there anything more to do except this three options , like changing the HT Frequency which is already by default at 4x ? Or changing the RAM Clock or something like that ?
And if nothing more to do, is it necessary to change the MSI heatsink or install a Fan on the nVidia Chip instead of the MSI heatsink already installed ?
I am sorry that I ask all that , because I am ever afraid to burn any piece of my PC , and this is why I am asking you because you made it already without problem specially that you have the same CPU as mine , but the different is the Grafik Card .
Thanks !

Neo2-F/A64 3000+/Zalman showing 40C at idle in BIOS v1.9!!

My Neo2-F w/ A64 3000+ Venice arrived last night, along with some other parts (will list full specs below). The BIOS version that it came with out-of-box is 1.9.
When I go to System Health in BIOS, it shows my CPU temp as ~40 degrees C!! I don't think this is normal for a 3000+ that is not being overclocked, especially at idle.
I even went so far as to get a Zalman 7000AlCu for it, and used Arctic Silver 5 (I followed the instructions for application on their website (put a beebee sized drop in the center of CPU, and lower heatsink straight down, then screw in bolts).
I have to admit, I did mess up the first application of AS5 ... well, not the application itself, but it was my first time working with a Zalman. So, when I tried to fasten the first bolt just a little bit as directed, the other side came popping up (too much leverage and I wasn't holding it firmly enough). I have heard that this can cause air to introduced into the AS5 compound, so I pulled the HSF out and cleaned both surfaces thorougly with alcohol ... cleaned each surface multiple times, even after I could see no more AS5 residue coming off.
I am aware that this mistake compromised the efficiency of this setup a bit, but shouldn't the temps for a 3000+ be closer to 30 degrees C at idle, especially with AS5?
Perhaps it's just BIOS v1.9 that is returning incorrect temperature values? What windows program can I use to check temps?
-Thanks!

My new 7000AlCu & AS5 is in a drawer...dont need them.
Try touching the very base of the hsf, closest to the cpu core as you can reach. BEFORE YOU DO IT, ground yourself by touching grounded metal objects.
Gives a clear indication if it's acceptable cool enough for YOU. I've had Abit AV8 mobo showing ~45C idle, next mobo was Asus A8V, showed pleasant 33C..current shows 27 and it's overclocked to 2,5GHz
I guess all temp readings are REAL CALCULATIONS, there is no real temp reader built-in...a BIOS matter.
Other things that add heat: RAM at high freq and voltage... SATA HDD's generate LOTS heat...bro's hdd got errors due to overheating, he didnt use fans blowing over the HDD...all that warm air makes cpu/case warmer ofcourse. You gotta have airflow in your chasse.
When/if you re-attach your HSF again, take a close look at the paste stuck on the hsf. I had "clear" spots (no contact between cpu core & hsf...paste doing no good) on ~40% of the core area....also I never trust AS5 again (or the boxed paste)...
Use Zalman's + some AS5: The two first times I re-mounted the hsfs (boxed and 7000AlCu) they were STUCK very hard to the core. Happened with alcu@as5 and boxed@boxed paste + boxed@as5. I've read "many" ppl ripping their cpu off the socket when trying to pull the hsf off...it got glued..solution=do it with warm pc).

Help me out, hard time understanding ratios? formula?(a64 3000 +neo4)

Specs are
k8n neo4 plat
a64 3000 venice
2x1gb corsair xms 3200
x800xl
520 ocz powerstrem
can some one give me there settings in bios so i can try them out, i want to try something moddest, im aiming for 2.2ghz maybe 2.4,
I really want to learn how to overclock but reading these guides are really confusing me, there seems to be a formula or ratio to how you overclock,
but im not getting it, its like a math formula isnt it? its freezing up my brain
can some one break down how the ratio or formula is done in order to get the desired overclock?
i understand that all setups will vary even if they are similar and my results will derive from my particular hardware.
i also understand the best way to know what your particular setup can handle is by testing the different settings at a time using programs such as cpuz, memtest and prime95..
any one mind helping me out? i chose this cpu for the sole purpose of overclocking it even though iv never even read about how to do it anyway thanks in advance.

The A64 boards only allow a few ratios, but lowering the memory speed to have tighter timings usually yields beter overall performance....
Value RAM usually has problems at the HTT's these A64 boards and CPU's can run at, but the "better" memory on the "right" board, can do cas2.5 at 300HTT....!
The typical ratios the 64 Bit BIOS allow are:
200 = 1:1 ratio with HTT and memory clock, so when HTT is 250 the memory clock will be 250
166 = 5:6 ratio, so when HTT is 250 the memory will be 208
133 = 2:3 ratio, so when HTT is 250 the memory will be 166
100 = 1:2 ratio, so when HTT is 250 the memory will be 125
Auto = I'm 80% sure that Auto = 1:1 ratio too
Some boards express these ratios in percent...

Msi Neo Plat & A64 3000

Hi guys
Well finally after a few months of waiting ive got rid of my stock A64 cooler and had chance to fiidle with some overclocking i really would like some advise on my recent overclcock perhaps some of you guys know where i might be able to tweak my system alittle bit here's the details
System
A64 3000+
MSI Neo Plat
2 X 512mb Crucial Ballistix PC4000
Radeon x800 pro Vivo
Hiper 450w PSU
60gig seagate IDE HDD
80gig seagate SATA HDD
Cooling
Thermalright SLK-978u
Artic Cooling rev4
so far i have reached this
FSB 235 x 10 @ 1.65v mem @ 2.5,3,3,10 @ 1.70v
temps are around 39
3DMark 2001 = 23766
3DMark 2003 = Havent try'd yet :p
So are my mem timings good ive try'd higher FSB but couldn't seem to get it without upping my volts, im thinking that it might be my memory settings holding me back but not really sure
Cheers for reading

Second double sided dimm in the 7030's seem to really give it headaches. WILL NOT run @ 1:1 no matter what I do. Automatically defaults it to 166 divider no matter what slots or bios settings I try. I managed to get them to run @ 200 by OC'ing to 240fsb but even then I had to use way worse timings than they would do by themselves. OCZ is the only manufacturer I have found that makes a 1 Gig stick that runs at the same timings as their 512 Mb sticks. When I get one of those babies I'll really be able to see what this thing will do @ 1:1. Probaly only get to 220 or so with pc3200 but doing it @ 1:1 with good timings will be sweet!

A64 3000+ OC success

Hello all.
I finally succesfully built my first computer... after i had to RMA my first Neo2... I felt like i'd never be able to get any of those nice results everyone was getting...
Last night i overclocked my 3000+ (1.8ghz) to 2.4 ghz and ran prime95 all night (over 8 hours) with not a single error or warning. I have to say it these little chips rock. My cheap memory is at 220mhz right now at 3-3-11 1T. Temps are low around 36-42... I am a happy camper.
The only thing that is dissappointing right now is that my vidcard is only running at 4X instead of 8X. But i think that doesnt give much performance difference... If i put it on 8x i get vpu recoveries as soon as i start a game... Anyone has any ideas what could be faulty... my mobo or my vidcard?
I tried all the combinations on bios to make it work for 8x but it just doesnt seem to like it...
My old coumputer i had my vidcard only running at 4x for about a year... because that was the max for my old mobo... so could that affect on this?

I did try to reinstall my vidcard drivers many times... still no go.
3) I will retry to install latest nVidia system drivers... any links that tell exactly how to do this...? like uninstall first the ones u have, then install the new ones... or is it straight forward... just install the new nVidia drivers over the existing ones ???
4) Do i have to uninstall vidcard drivers before i install the new nVidia system drivers n then reinstall em again?
And i am changing from 8x to 4x using my Ati Catalyst Center latest version, not Bios.
Thnx for ur replies.
1 - 67 locks AGP freq
2 - install GART, it's part of the mobo S/W. Get the unified driver set for the Nforce 3 here- http://www.nvidia.com/content/drivers/drivers.asp. Just install it all.
3 - Straightforward
4 - Nope. But you can after the mobo drivers if you want. I'd do it just to cover all your bases... You might benefit from doing a complete uninstall of the ATI driver w/ Driver Cleaner (google for it - I forget the link). It will get rid of all traces of the old ATI install, so you can start fresh.
Change to 8x in BIOS would prob work best.

Low CPU mark score with a64 3000+

I get around 650 to 680 cpu mark score with my system:
MSI Neo Plat
1Gig of PC3200 KINGSTON Ram
A64 3000+ @ 2ghz
Leadtek 6800
I've updated the latest nforce drivers from MSI and the bios is 1.2
I think it's way to low since I had 300 cpu mark score with my lousy Athlon 1.4Ghz thunderbird.
I see that other a64 3000+ users get around 800 to 950 cpu mark score. Why is mine too low? Bios settings? What should I check?
I see even a MSI Kt800 user with 840 cpu score!

Could you please post a link for the software benchmark that you are referring to? I can't seem to find the right one. I got something called CPUMark but it is scoring mine at like 3400 which isn't in the correct range based on what you've said so it's probably a different software. Thanks for your help. I just want to see where mine falls out.

Overclocking help--A64 3000

I know there are countless threads on this subject, but I'm gonna post this anyway, lol.
I have an Athlon 64 3000+ on MSI K8N Neo Platinum (BIOS 1.1). I have 2x512 Mushkin Level One pc3500 in DIMMs 1 and 2. I'd like to achieve an overclock of 2.3-2.4 if possible. Right now the best I can get is about 2.2 but I haven't tweaked much.
Several questions:
should I set 1T or 2T
should I enable or disable Spread Spectrum
Should I change AGP frequency
what do you recommend for CPU voltage? I have a Thermaltake Venus 12 hsf
does lowering Hyper transport from 4x to 3x negate the effects of overclocking?
Any other advice would be helpful, as well.

1t will yield better performance. 2t might possibly give you a slightly better overclock. Most people say it isnt worth the performance drop.
Disable Spread spectrum
Set AGP to 67
CPU Voltage could be set at 1.65v safely i've heard. I dont think I would set it higher than 1.6v but i'm on stock cooling right now.
lowering hypertransport from 4x to 3x shouldnt be so bad... usually you wont have to until youre approaching about 240 HTT Frequency
I might suggest updating your bios to one of the later ones and maybe a beta one. That is if you want to achieve high HTT frequencies. ie greater than 230ish.

Problem overclocking A64 x2 3800+ with K9A2 CF !

Hi there, I have an A64 x2 3800+ (windsor) on a MSI k9A2 CF (AMD 790X) with a pair of GeIL 1Gb DDR2 800 CL4 (4-4-4-12) and I'm trying to boost it up...
I've followed some guides and I was able to determine the maximum speed of each component.
With a 3x HTT multiplier and a memory divider set to the lowest one, the computer was stable at 260mhz x10 @ 1.45v (2600 mhz)
With a 3x HTT multiplier and a x9 CPU multiplier, the memory was very stable at 250mhz with a 1:2 divider (1000mhz) @ 1.95v.
I was able to run succcessfully the AMD Overdrive stability test, SUPER_PI and 2 instances of prime95 with the FSB at 250mhz x10, and DDR@1000mhz but the HTT set do 3x(750mhz), when I set it to 4x (4x250=1000HTT) I start getting this message at boot:"DQS Training failed on previous boot, revert to slower DRAM speed" and it sets the memory to the next highest divider (1:1.66 I think?!?).
Am I doing something wrong???
Thx and cheers to all

No. For stability keep it below 1000. If it's at 1000 now at 4x then drop it to 3x
>> Read this <<
Memory controller is in the CPU.
Edit: Of course if I'm wrong with any of this I'm sure someone will jump in & say so.
won't bother me me as long as you get what you need.

I having trouble getting over 1.97 on A64 3000

I raised the fsb to 219 but it seems not to get passed that its idles @ 36 so I dont think its heat is there some other setting I need to adjust?

Quote from: Sharp on 14-April-05, 22:00:14
Hello,
You may need to change the hypertransport multiplier/ratio.
From x5 to x4.
Or you memory cannot handle the extra 19Mhz, change the CPU:Dram ratio to 6:5 and see what happens.
6:5 will make the memory run at 182Mhz (not overclocking it)
Thanks for the tip anymore you could share with me plz I would be most greatful

My A64 3000 CG stepping @ 2.4Ghz - but is it safe running at 1.7?

Well, my question is stated in the subject
I use a zalman copper cooler, the really big round thing lol
Temps never go above 45... so I'm assuming 1.7 is ok? Or can it fry regardless of temperature?
Thanks for any replies

Hi !
I am back
heatsinked, or anyone who knows, I tried to go to 240 for my CPU but the Windows then didn't start then restarted my PC.. After that I got error message that windows can't start because a File is missing , anyway I entered the Windows but I went back to 230x10 ...
Now anyone knows why this happened ? Does my ram not allow me to go further ? Or is there something else stops me to go to 240 ?
How could my settings in Bios be ? Settings of CPU and Ram and anything else I need to do to get to that 240 ?
Thanks for any comment!

Overclocking and to D.O.T or not to D.O.T?

First off, please forgive my very newbish question here. While I have built a couple of systems, this is my first journey into the world of overclocking.
A bit of background:
The rig I have built in my sig, with no overclocking, has been performing very well and rock solid with gaming and general use for 8 months now. I have just started to venture into the world of video editing and converting my videos into a format that can be streamed. That is when I hit the performace wall, and realized for this kind of CPU hungry use I needed to either upgrade my build after a pitifully short 8 months, or look into overclocking my system to squeeze every ounce of performance I can get from it. Not having wads of cash readily available, I decided to get my feet wet in overclocking.
My first foray into overclocking has been to just stick my toes into the water and let the system overclock for me using the D.O.T options in the BIOS. Doing some experimenting, I have found that I can get some fairly good gains in performance ~+10% in benchmarks by simply bumping the D.O.T level to 'colonel'. The 'general' setting is unstable, giving me the BSOD whenever the overclocking kicks in.
Here is some hopefully relevent info on my setup. This is the CPU-Z display when D.O.T has kicked in.
Temp wise I go from 37C (idle) to 47C (Overclocked Load)
And here are my benchmarks when using D.O.T: (3DMark05)
Main Test Results
3DMark Score 5321 3DMarks
CPU Score 5156 CPUMarks
Okay, now to the meat of my question.
How much CPU headroom do I have on my hardware, above and beyond what I am getting with the D.O.T settings I am using? I have reached the limit as far as using D.O.T('general' setting being unstable), but could I get significantly better gains if I manually overclocked?
Or.. would I be better off staying ignorant of the mysteries of manual overclocking, and just save my money to one day buy an Athalon X2?
Thanks!

first of all, if you are using DOT, you have no control on the OC. the system is overclocked using some defaults settings programed into the cell chip. that means that it doesn't take into consideration the hardware you are using, and its limitations. this might result in instability.
second, the max OC with DOT is 11% if i remember correctly. that is a puny OC attempt, especially if you are running a A64 3000+ like i do. i can get to almost 50% OC for the CPU using different methods than DOT, instead of 11%.

K8NGM2 working with AMD64 3000+ problem

Hi
I have a K8NGM2 working with an AMD Athlon 64 3000+ Processor. It is woring at 1800 Mhz and i can´t set it up to work at 3000. How can I do it? Since the setup of the BIOS do not save my changes.
I´m looking forward for an aswer.
Thanks!

that should be a sticky something for the hall of fame
hugoar, like dr stu said, the AMD A64 3000+ runs by default at 1.8GHz. the 3000 after the name is only a marketing designation for the CPU which shows that the CPU will have the same performance as a Athlon Thunderbird overclocked at 3GHz.
