Both are toledo cores. Anyone know if the 4400 will hit just as high of a frequency as the 4800 overclock vs overclock?

Just higher multiplier to play with if you have an underperforming (*hint hint*) mobo.

Both will reach just below 3Ghz on air with luck.


The 4800 has the higher multiplier?

I’m finding 2500MHz to be a wall with a VCC of 1.45V on my new X2 +4400, I can go higher but I don’t know if the higher temps and VCC needed is worth it (1.5V @ 58-60c). But I’m still slowly working my way up to 2600MHz.

What kinda cooling you got?

I'm the same. X2 4400+ @ 2.475GHz without any voltage increases on air, but scary enough temps on load to not put it any higher. (By scary I mean 55ºC in the summer - generally AMDs shouldnt go above 60)

I have a 4400+ and I can get it to 2.5ghz at 1.475v. But to get to 2.6ghz I have to run it at 1.55v. I would go for the 4800+ you have a higher multi and you are running 2.4ghz at stock. The chips are the same, the 4400+ is at 11 multi and the 4800+ is 12 multi. I would think you could get a higher clock out of the 4800+.

HTT = 1052MHz
RAM = 416MHz, 2.5-3-3-6 T1
53c on Prime95 running on both cores.

4800 here.Playin with short time.Here it is so far.H20 for cooling.
12x234=2808
cpu volts 1.5
2.5-3-3-6 1t@2.7v

8hrs stable on sp2004 orthos.

Thats exactly where I am with my new X2 4800 but I am on air! Using the Artic Freezer Pro 64 and my temps at this speed are 35c idle and 47c load. 8)

At 2880 now.What stepping you have?My core 1 runs a little less then 47c.Core 0 always 3c-5c less.My stepping.Nice job on air :D  .

I've hit 2.8GHz on my X2 4800+ but I don't like having my CPU voltage that high when the performance difference is so small.

You did remember to pull off at least one Bungholiomark at that speed didn't you? That's what 1.75-1.80V on Toledo are for. :wink:
I forgot to check how many Bungholiomarks I could get. :( 
August 23, 2006 5:32:21 PM

Wow, that’s a 400MHz over stock increase with only a 0.15V VCC increase. That’s 133MHz/0.05V.
The best I can do is 100MHz/0.05V w/o errors in P95.

PS. That’s based on a theoretical stock voltage of 1.325V VCC

I don't see why everyone changes the standard air cooling solution to something after market.

I have a 4400 on a ASUS A8N-sli deluxe and I am getting a very stabel 2.53ghz on only 1.4 volts. Multiplier is 11 hyper transport is 4. CPU freq is 230 i think.

The idle temp is 30c and it hasn't got hotter than 48. I just have had very good experiences with this stock cooler, especially since it has heat pipes standard.
September 23, 2006 4:19:34 AM

unfortunately the multiplier is locked at 11x on the 4400 whereas the 4800 is 12x.the 4400 will reach 4800 speeds but not with the multiplier.awesome cpus bothe.goodluck.

I have the stock heatsink on my 4400+ and love it my temps are 30c Idle - 47c load! I want to get the xp120 to realy get my temps down and see what this chip can do! I have seen guys hit 2.8ghz - 2.9ghz but with IHS removed.
April 19, 2008 5:12:00 PM

I have an 4400+ and I have been able to hit a max right at 2.8, thats with 1.5volts, I keep it at 2.64 now for temprature and stablity reasons.

Is there some sort of time warp here? This thread was made in 2006.

lol Timewarp.


I thought I was the last one left sill running a 939. Mine actually runs most games fine, even being a single core. See the new Tom's artical on 939's on gaming? Mine runs HL2/Counter Strike at 195fps and BF2 pegged at 100fps. Suffers on Crysis and the new stuff. The 980GTX i just install seems to run physx demos smooth.

I finally got mine running up to 2.8ghz stable this spring. I learned about the ram ratio.

FSB = 255x11, = 2805ghz stable
CPU = 1.45v
RAM:BUS = 6:5
RAM = cqc = disabled, 2.5-3-3-7 x4 Mushkin DDR400 @ 2.7v

Now, I've been playing with volts, ram timings, and drivers. I had to flash my Ram with SPDtool to get 2 gigs working on a DFI Lanparty NF4.

I just shoe-horned in a 9800GTX, and retired my 7950GX2. All the new 280's and 260, 4870's are really long length.
The new video card covered my SATA ports, so I had to dremel away a bit of the cover to get my harddrive cables to fit in.

heres a photo of mine compared to a Phenom quad core with a 7950GX2:



I think in 2009 when the 45nm AM3 Phenoms come out I'll retire this old single core.

I have a X2 4400+ in my secondary system.I have it running at 2.8ghz stable with 1.5v on air,using an evga MB.I was able to get it to 2.9 and load windows,but wouldn't run any benches.My temps are 42c idle and 57c under load.I have had it running like this for just over a year now with no problems.The Toledo cores seem to oc quite well.Goodluck.

my x2 4400+ doesn't go past 2.3 stable, even with 1.5-1.6v. Boots 2.75 but doesn't go into windows. I'm on a msi board, neo4f deluxe.
November 13, 2008 5:35:43 AM

Its not the volts or the bus. its all about the RAM timing. set it to 2.5-4-4-4-8 and crank it to 233, OR set it to 2.5-3-3-3-8 and move the ratio to 6:5 or lower and remeber to adjust the hyperthreading ratio to 5:4 or 1/3. AMD's do like the hypertheading over 1020mhz and the RAM does not like to go over 420mhz

If you keep the memory within spec, you can pump the bus up to 255mhz, to get 2.8ghz and have it run 50% faster than stock (depending on your hardware)

My x2 4400 is almost 3 years old now, and its been stable @ 2398 / 218 ever since, im looking to push it though, maybe even kill it by running it stable at stupid high temps. See how much i can push out of it before i upgrade to an 8 core, even thought thats probably 2 years away i could probably use a break from the computer world.

Currently running my 4400+ x2 toldeo @ 2.75ghz stable with stock vcore :o 

cpuz validation page: http://valid.canardpc.com/show_oc.php?id=474464

i have OC'd it to over 3ghz stable at 1.45 vcore.

I'm currently #25 on the world overclocking database for this processor :D 
January 15, 2009 1:55:33 AM

I have been reading this thread among others for inpiration for tips and to see what others have done to overclock. My specs are as follows:

Mobo: MSI K8N neo4-f
CPU: amd 4800+ x2 toledo
RAM: OCZ Platinum ddr400 4gb

So far I have been able to accomplish a little over 3Ghz completely stable. I am very comfortable with these settings and thought that I would share with anyone curious.

I first started off by lowering my memory clock. IMO this should always be your first step to overclocking b/c once you start overclocking the fsb the memory goes up with it. I found that a speed of 166Mhz worked well for me. I found that pushing the HT over 1000 gave me stability issues so I kinda want to say as a rule of thumb keep this value as close to 1000 as possible. B/c of the HT > 1000 stability issues I chose to lower the HT multi down to 4x. I then increased the fsb to 240. What you will notice is that my ddr clock increased back to 200Mhz. I can get higher speeds with my ram but have determined that it is best to stay around where the memory is rated at. This gives me a cpu clock of 2880Mhz. After booting and trying to run 3dmark06 I was running into bsod and memory dumps. Increasing my memory voltage by 0.05v fixed this. 3dmark06 then ran fine untill the cpu test, the program would crash but windows would be fine. I then went to my vcore and increased it to 1.43. I ran 3dmark06 again and cpu test ran for a while then it crashed again. Increasing the vcore to 1.483v fixed this problem. I then enabled the dynamic overclocking bios function that came with the mobo. I set it to overclock 7% and ran 3dmark06 again and whaallaaa! I am running over 3Ghz with a max temp of only 49 C. I have a zalman cooler and highly recommend this brand for air cooled systems. I was thinking about posting my ram timings but figured that everyone's config will be different.

I have oc'd a bunch of processors and am impressed with these chips. I definately know I can push this chip further but I'm gunna have to pull out 2Gb or ram to do it I think. Hope this helps anyone trying to oc the 4800+ toledo.

I'm new to overclocing AMD chips. I'd like to mildly oc my 4800+. What temp monitoring application do you use? What are the max safe temps?
I just changed my BIOS on my ASUS mobo to enable dynamic oc (AI NOS) and enabled up to 5% oc. Running prime95 right now and using CPUID Hardware Monitor my Core 0 temp is max of 58c & core 1 is max of 54c. Core speed is 2520. Whoops.... Just had a error.
Thanks for explaining how you did it. Steve

Steve,
I am very new to OC'ing.

I use Core Temp for temp monitoring. http://www.alcpu.com/CoreTemp/

I think 60 C would be as high as you would want to go. Even then....I really don't want my chip over 55 running at 100%.
In fact I think it will crash before getting to 60.

Anyhow I have a 939 4800 x2, 4gb of Kingston and Mushkin ddr 400 mhz ram.
theses settings have got me loaded up...but...i would not call it entirely stable.
217 x 12, 1.45 v, 3-3-3-8 2t, and HT is set at 4.
