Hey there overclockers,

I am attempting my first overclock, and I could use a helping hand in getting my 2.4GHz Athlon64 3400+ to 2.6GHz. I am using stock cooling and cheap components but 200MHz isn't too much to ask, right? ;)

For reference, my other hardware is as follows:-
- An Akasa Paxpower Version 2 (url) 460w power supply.
- A Gigabyte GA-K8NE (url) socket 754 motherboard.
- 2x 1GB Corsair Value Select PC3200 (2.5-3-3-7)

I am currently using these settings: -
(This section will be updated as needed.)

- FSB: 216
- Multiplier: x12
- HT: x3 (x4 no boot)
- Memory: 166MHz
- Voltage: 1.700v
- Clock: 2598.5MHz

The PC will not boot with the HT at 4x, so I have set it to 3x.

The CPU failed Prime95 at 6min at 1.525v and 1.550v, and at 30min with 1.650v. I just attempted 1.700v to see if there's any more stability, it managed 55min before an error. You think I can leave it as-is and consider it "semi-stable" until I get some aftermarket cooling etc. for it?



The temperature of the CPU has not yet broken 57ºc so cooling is fine.

By the way, does anyone know what the speed rating would be with it overclocked to 2.6GHz? As far as I know the 3400+ is the highest rating on socket 754 so I have nothing to compare to. :confused: Am I right in assuming 3700+ would be correct?

Sincerely yours,
Exsomnis.

bit more info required, m/b. memory.psu
try setting cpu volts to 1.55 as it looks to be under volting at 1.525
you can leave htt@4 unless you go over 250.
 
Could a mod please delete my last four posts in this thread (including this one)? I deleted them to condense all the required info into one post. Thank you. :)

Might be a bit out, and I dont have any NF4 Mobo myself, but have you also tried setting the AGP speed to 67?

On a couple of my NF2 and NF3 boards, they dont lock if they are on AUTO or 66, but they do lock if you set it manually to 67.
 
That's a 130nm cpu no? Give it some volts!!!!
I have a sempron64 which is essentially the same chip but on a smaller process and I have more volts going through mine than you do!!!

BTW just incase you didn't know a smaller process (ie 90nm compared to 130nm) requires and can handle less volts than a larger one

I have only used 1 nforce 4 mobo and it auto locks the pci frequency and pci-e frequency

I was actually puzzled about this, because when I went to reduce my PCI-E frequency, the lowest possible setting was 100MHz (which it was already set at.) I assumed from there that it auto-locks the PCI-E/PCI/etc. when adjusting the FSB, and I hope I was right. :(

Yeah, it 's a 130nm CPU currently running on 1.55v. Would you say voltage is still my problem, and what would you say is a safe voltage?

Edit: I'm going to try my settings for 2.6GHz again now, but this time with 1.65v.

I just ran Prime95 and got an error after 30min, which is a lot better than it was originally doing. The CPU isn't breaking 52ºc, is there any way to improve stability? The voltage is at 1.65v at the moment, and has been improving stability every time I increased it. Does it need more?

Edit: Trying 1.7v.

i have the same CPU and i've just got some 2GB G.Skill 3200, my luck with overclocking sucks but so far with HT at 3x and FSB at 250 x 10 it seems okay but i've left it back on default as i dont see the point in underclocking my ram (set to 266ddr) for an extra 100mhz. (unless someone can tell me otherwise as i'm still new to this).

Well the reason I did it is because my CPU is a (pretty huge) bottleneck for my graphics card, so I'd rather sacrifice a bit (and it is only a tiny bit really) of RAM speed for more CPU power.

My RAM speed has gone back up to something like 178MHz anyway because of the adjustments (had it set on 166MHz) so it's no big loss. You should just go for it, the improvement in CPU power is going to be more beneficial than keeping a little RAM speed.

if you set your divider to DDR333 your ram should be running at around DDR400 with the overclock. :)
 
As the post above, I think you will definitely need to run a divider as the Corsair Value select range does not have a great deal of overclocking potential and is really only designed to run at PC3200 speed.

The 3700+ (754) runs at 2.4 stock with L2 cache 0f 1mb

Correct me if i'm wrong but the 3400+ has a 512 L2 cache ?

Have read that the 512 diference in L2 cache equates to approx .2 ghz in preformance.

So your benchmark would be a stock 3700+ .

Cheers,

mark
 
no the 3400+ can also have 1mb cache as well, depends on the core, clawhammers have 1mb L2 cache, while the newcastle core only has 512kb. thing is though, the clawhammer cores have double the cache but are clocked at 2.2ghz, while newcastle with 512kb are clocked at 2.4ghz
