OC Capability of the 4000+

I'm new to OC myself and I've been trying to read extensively as well. I have an Athlon 3700+ San Diego. Right now without messing with voltage (I left that at Auto in Bios) my CPU is at 2.7 GHZ with FSB of 1078.

All I did in bios was set the frequency clock to 270 Hertz, multiplier to x10 and FSB/HTT Multplier to 2.

From what I read its better to have your frequency clock higher and multiplier lower than the other way around. Give it a go.

System can have some stability issues if HTT clock gets past 1000 MHz (Socket 939.)

You lowered your HTT multiplier a bit too low, 3X would be okay cuz it doesn't go past 1000 MHz
 
overclocking will void the motherboard warranty too, i 99% guarantee it.
btw don't get an X2 if you have a 4000+
i've heard of "reverse hyperthreading"... sounds like it wouldn't be good, but instead of one core working on multiple processes, its two cores working on a single process. this means that dual core works twice as fast on gaming and such--- also wait for AM2 + conroe.
another thing, i've heard of a new type of component to add to gaming systems... a "physics processing unit".. this would release stress on the processor, and have another part specialize in.. well, the physics of the game.
anyways, these are just a few reasons to wait.
 
Already waiting on the physics card. Want a low end x2 to OC. Nothing big.

I am almost posative I can get this to 3Gig, just need the right hardware. Got it to 2.68 today, but had to up the mem voltage by .25. don't know stability yet, but I don't think it will be a problem. I believe I can get to 2.8 on stock volts for CPU, but I don't think it will be stable...so I'll kind of shop around for info on Mhz to E ratios posted by other OC'rs to avoid the guessing game and the real possability of CPU murder...

Most companys will still take back enthusiast boards if something happens to them during overclocking, as long as its not physical damage or something stupid. If something does happen to your board Machine7587, (assuming you ordered from newegg) RMA through newegg, not DFI, because their RMA service is pretty much crap.
 
Yea, I already did one...I now have two DFI MB's...one for OC, one for backup... =)

My PSU fubared the other one though. after I had hooked it all together, it wouldn't boot, so started TSin the system. Had it out of the case and on the bench looking at it all when I noticed the 3 1/2 floppy 12v connector had a 12v+ and GND crossed...I was using that for board stabalization. Burned the votage reg...glad I didn't pop the CPU.

As for the CPU, It was unstable at 2.68. Dropped out at the first sign of a load. So I'll have to start looking at voltage increase...

Fun.

if no physical damage was done, you either wouldn't send it back... or they would simply send you back the same board. they most likely won't replace it.
lol unstable at 2.68ghz... of course. instability means not enough voltage or too much frequency. what are the temps at 2.68ghz?

Well my PC is definitely a socket 939. The FSB right now is at 1078.78
My CPU is running at 2.7 GHZ

Everything seems stable and full load temp caps at 47C. HTT Multiplier is at 2, but if I raise is to 3 won't it go higher than my current FSB i.e. 1078?

Here are my parts.

I have an Asus A8n-SLI Mobo
AMD 64 3700+ San Diego
Zalman LED Cooler Fan for CPU
Microstar 600W Power SUpply
Corsair Valueselect Ram 1 Gig
Geforce 6600 GT Pci-E x16

U said your CPU is running at 2.7 GHz, you also mentioned that the multiplier is 10X, so 270*10=2700 (CPU speed) and the HTT will be 270*2=540 (too low), 270*3=810, 270*4=1080 (yet too high), if it goes past 1000 MHz it can cause instability (I didn't say it will, but it's possible).

My suggestion, set the multiplier to 11X, FSB to 250 MHz, HTT multiplier 4X and you will have it running at 2750 MHz with a perfect 1000MHz HTT.
 
Hmm, thanks for that tip. The only question I have is, how come my FSB is showing at 1080 right now? and not 540 that you posted? Is my reading wrong?

Are you sure your HTT multiplier is set to 2X, if it is then something is wrong with the software you are using (I think it's set to 4X).

I'm positive its set at x2. But I'm wondering. Someone told me this was a marketing ploy but my board, Asus A8n-SLI is set to have max FSB/HTT at 2000. But people tell me thats just some new gimick where I have some special HTT with an AMD 64 which kinda doubles my FSB but not really.

And when you look at the numbers, if the Mobo is doubling it, 1/2 of 1080 is 540. What your numbers say. Do you think thats the case? Cause from what I've been reading your equations are exactly right. And that also might explain why sometimes Winword sucks my resources like a crack addict.
 
Can you tell me what software are you using for reading your HTT. Try the one I already posted. Mine is 250*4 and it says exactly 1000 MHz.
 
With my motherboard comes a program called AI OverClock. Since I've gone manual its disabled in my BIOS. But it still monitors everything from CPU, FSB, CPU Temp, Mobo TEmp, PCi Voltage, core votlage etc.

I checked the temps with Asus Probe II and it works out and the CPU usage also check out so I don't think its giving me faulty readings. I'll try you program to check though.
 
You were right, its readings at 2.7 GHZ and FSB is at 540. Wow that means before I Overclocked my FSB was at 400 this whole time. I wonder why AI OverClock was giving me a reading of 1080.
 
Don't know why it was giving you the wrong info, I'll install it now and see if it does the same thing to me. You know what to do now, go into BIOS and change that.
 
I did exactly what you told me in your previous post. frequency 250 Hz, x11 multiplier, HTT multiplier x4. Booted up no problem. Loading windows seems a bit faster but I don't know if tahts my imagination.

I checked my AI OC program and your other program. They finally agree. Both show FSB to be at 1000. Which is good but odd to me since last time it was

Previous
2.7 GHZ FSB 1080
Now
2.75 GHZ FSB 1000

But heck, I'm glad its 1000 now and not 540 as before. Thanks so much. LoL. I don't want to look at a gift horse in the mouth but do you know much about RAM as you do this? :-)
 
Yes, I can help you with RAM too, just say what you need.

To your question: It's 2.75 GHz MHz cuz 250*11 equals 2750. Before it was 270*10.
 
My ram is cheap so I don't know if I should just leave it alone or if I can push it to be better. Its a Corsair ValueSelect pc3200 (200 Mhz) 2 sticks of 512 MB. Exact serial number is VS512MB400 its running dual channel.

going by the program you sent me. Here are the stats of it.

128 bit interface.
Clock Frequency 161.76 MHZ
DIMM ECC Disabled

Read CAS# Latency 2.5T
Precharge to Active 3T
Write Recover Time 2T
Row Cycle time 16T
Row Refresh Cycle 16T

Write CAS# Latency 1T
Active to Precharge 6T
RAS# to CAS# Delay 3T
RAS# to RAS# delay 3T
Enable 2T Timing Yes

DIMM Refresh Rate 133 MHZ.

Heres what CPU-Z says.

Frequency 161.8 MHZ
FSB:DRAM CPU/17
CAS# 2.5
RAS# to CAS# 3
RAS# 3
CycleTime(tras) 6
BankCycleTime(TRC) 16
DRAM Idle Timer 16
Command Rate 2


I really don't know what those numbers mean. At my old settings, before I used yours, I remember the FSB:DRAM setting used to be at cpu/15. Thats about it. Let me know what you think.
 
Ok, do this:

Go to BIOS and set RAM speed to Auto (so that everything about RAM timings changes to default cuz I can see some of them are wrong)
Reboot
Go again in BIOS:
-Change RAM speed to 333 MHz (your RAM will now run at 200 MHz (DDR400) cuz of the memory dividers, speed what it's suppose to run at)
-Change Command Rate to 1T

And this is it.

EDIT:

I have the same memory (2 x 512 MB in dual channel), these are the timings:

DDR-SDRAM
DRAM Size 1024 MBytes
DRAM Frequency 204.5 MHz
FSB : DRAM CPU/11
CAS# Latency 2.5 clocks
RAS# to CAS# 3 clocks
RAS# Precharge 3 clocks
Cycle Time (TRAS) 8 clocks
Bank Cycle Time (TRC) 11 clocks
DRAM Idle Timer 16 clocks
Command Rate 1T
