wat sort of overclock can i expect from this? ive only mucked about a little bit with overclocking but i want to see hoe far i can push this. i have asusa7n8x (nforce2) 2x256mb pc3200cl2 ocz ram and 450w psu. will i need to modify the cpu to get maximum oc from it? will ibe able to use all the multipliers?

ok first the good news... my new xp1700 arrived this morning at 7.30am!!!! i ordered it yesterday afternoon! and thats just the standard free delivery... i dont care what anybody says THAT is SERVICE!!!!
ok now the tech stuff.. its week 19 03 date which makes it 4months old (approx) we are in week 34 now. i dont remember the code on it and its a 1.5V part. and the bios temp reading is 25c
now the not so good bit..
1. how do i unlock the higher multipliers? i can only get up 12.5
2. the bast*rd wont take 166fsb above a 10x multiplier or 200fsb above 9x
3. at 133fsb i can take it to 12.5 multiplier without probs but i cant access higher multipliers grrrr!

so how do i get the higher multipliers and am i doing something wrong or do i have an exceptionally crap chip?
specs are
xp1700+ ..well duh :evil: 
2x256mb pc3200cl2 ocz ram
nforce2 (asus deluxe)

c'mon people help me out here please....
how do i unlock the higher multipliers?
August 21, 2003 1:20:41 PM

a7n8x can't go above 12.5 for some chips. I tried OCing my 2800 and whenever i tried to use 13x it would not boot up.

bloops!
August 21, 2003 1:30:51 PM

it will go over 12.5 as long as the default multi is already over that i believe. i think you have to join some bridges on the cpu in order tp activate the higher ones.. im just waiting for someone who has the knowledge to come and share it
August 21, 2003 1:34:55 PM

I'm definatly not that person with the know-how :D

ive read it a few times in various place but never bothered to make a note or keep a link cos i never needed to.....
now i need to i cant find the *&^%$£""£$% information!!
August 21, 2003 6:05:54 PM

Ok first off, you have 3200 memory that will run 200mhz and a board that should do 200mhz. You shouldn't need the higher multi's. If your running at stock voltage, try 1.75 volts and try 200x10 = 2000mhz. My 1700 needed 1.8 volts to do 2.3ghz. Use prime to test for stability. If it fails, add more voltage or lower fsb. Did you take note of the core colour?

Finally, only a few boards give you ALL multi's. Most just give you the range that your cpu is in, for e.g a cpu with 11 multi will have upto 12.5 available.

With A7n8x and Tbred XP1700+ you need to mod the L3 bridges or do a socket or pin mod to get the higher multipliers. See link below (about middle of page) for the socket and pin mod.

The socket mod is the best because it's the easiest to do and easiest to undo.

<A HREF="http://www.beachlink.com/candjac/Workarounds.htm" target="_new">http://www.beachlink.com/candjac/Workarounds.htm&lt;/A>

Basically all you are doing is enabling the 8x multiplier bit which forces the high range of multipliers. Connect a fine wire strand from socket hole AJ27 (8x bit) to AH26 (Vcc, Vcore). That's all there is too it.

ok thanx for the info.. i upped the voltage to 1.65 last night but i got no improvement.. at 166 x 10.5 its 100% stable. at 166 x 11 it WONT EVEN BOOT! is that normal? i would expect instability going in small steps like that not just a refusal to work? its like amd somehow artificially put the brakes on the oc ability of the chip! like limiting a cars top speed.
August 22, 2003 1:55:33 PM

Won't boot at 1833 Mhz? Almost sounds like you have a Tbred A. Check the second line of info on the chip below the "AXDA1700DLT3C". JIUC<font color=red>B</font color=red> or JIUH<font color=red>B</font color=red> would be a Tbred B. AIUG<font color=red>A</font color=red> would be a Tbred A. These are just examples but see how the last letter indicates whether it's a Tbred A or B.

Whatever you have try yet higher voltages. I need 1.7 volt Vcore to get above 1800 Mhz with my Tbred XP1700+ (JIUHB B, DUT3C, week 0302) and 1.8 volt to reach 2100 Mhz.

About you're need to get the higher mults, well don't bother. If you get to a 200 fsb then forget about the higher multipliers, it just won't work.

200 fsb (or higher) stable is what you should be aiming for Increase ur VCore to 1.8 don't worry as long as your cpu temps are below 55. Increase the VDimm to 2.8, put your multiplier down to 10 and then put ur ram timings on default or auto and start stepping up the fsb.

overclocking is not easy, but it is fun and interesting (for me) but tiring and you need patience. There is a very good guide, please read this, it teaches you that there's not only 1 or 2 reasons why you can't overclock anymore, it's more like 7 or 8 reasons. One thing I didn't see on that guide was that an overclock might also not work because the psu is under too much load too. The guide is for the A7N8X, but it's still a good one and useful for other AMD mobos.

Good luck.

thanx. i doubt its a tbreda with the manu date it has on it week 19 2003. i tried 1.75v (highest mobo goes to) and i got 200x9 (1.8ghz) stable. 200 x9.5 gives me windows errors
or i can have 166x11 (1.833ghz)stable
how can i get higher voltage?
August 26, 2003 1:04:28 PM

ok i just went home stripped my current cpu out put in the 1700 and run cpu-z. it says it a tbred 0.13 stepping a0. im guessing that means tbreda right? only i thought amd introduced the tbredb's august last year? anyway full code is: AXDA1700DLT3C 9324518250286

Without doing a soldering mod to your motherboard the most you can get is 1.85 volt (plus whatever increment your BIOS allows). You can do this a couple of ways.

One thing you can do is change the default voltage on your processor. The L11 bridges control the default voltage. If they are all closed you have 1.85 volt.

After filling the trenches with something non-conductive use conductive paint to close the L11 bridges (those that are not already closed). Now you have 1.85 volt default.

If your motherboard formerly allowed a 1.75 volt when the default is 1.5 volt that repesents a 0.25 V increase. Now you would probably be able to go to 2.10 volt. If you default is 1.6 volt then the increment is only 0.15 volt and you new max would only be 2.00 volt.

Your other choice is to do a CPU or socket mod. you essentially make the same connections as above but you do it on the backside of the CPU or on the socket. See this article (wait for the overlay).

<A HREF="http://www.ocinside.de/go_e.html?/html/workshop/pinmod/..." target="_new">http://www.ocinside.de/go_e.html?/html/workshop/pinmod/...;/A>

The article shows a picture of modifications to the CPU but you can also insert fine wire threads into the correct socket holes to do the same thing but remember the socket is a mirror image of CPU.

Also, as hatimh knows, if you are only increasing the voltage you don't have to cut the L11 bridges. Nor do you have to duplicate the connections that are already on your L11 bridges.

It's up to you what you choose for a new default but remember the new default is probably the lowest that you can set your voltage in BIOS. That is, if you set the new default to 1.85 volt you might not be able to go lower than 1.85 volt (depends on the motherboard and the BIOS). You would have to "un-mod" to go lower again.

The voltage options all depend on the motherboard and BIOS but if you mod the default to 1.85 you would be able to get 1.85 volt at the very least.

hey did you order from newegg?? In that case, you should have read the reviews.... I don't know why, but AMD stopped with the JIUHB stepping and used the A cores for the later dates...who knows...
August 26, 2003 7:17:53 PM

Just looked at the reviews.

Oh crap! AIUGA 0324!

I thought Newegg customers were still getting old stock but the customers are reporting dates of manufacturer like 2003, week 24 !!!!!

Are these a trial run of Thorton cores? I hope not. They're pitiful compared to the JIUHB DLT3C cores.

i didnt order from newegg i got from dabs.com
i get most of my stuff from there as its based in england and im english.. very good delivery and service. havent neede to use their return policy yet so dont know what thats like.
anyway... so what are you saying? i have a poor chip for oc? i have a tbreda? why would they be using the tbreda core 6 months after they switched to the b core?
August 27, 2003 1:36:29 PM

You confirmed it yourself in your other post, "AXDA1700DLT3C 9324518250286 AIRGA 0319WPMW".

AIRG<font color=red>A</font color=red> means it's a Tbred A. 0319 means week 19, year 2003!

This surprises everyone and it sux!

Tbred A's historically have only overclocked to about 1.9 Ghz unlike Tbred B's which usually overclock from 2.1 Ghz to 2.5 Ghz.

Those user reviews at Newegg state that other people are receiving these new, year 2003, Tbred A's and that they don't overclock all that well. This implies that they are not just relabeled processors but in actuality are Tbred A's.

I don't know why AMD would do this.

AMD is planning to bring back the Duron brand. Perhaps they will use Tbred A cores just to limit performance.

now i think about it does kinda almost make sense. t bred b have extra layers yes? so they would be more expensive to manufacture? does that make sense to nayone else here or am i chatting from my arse again?
August 27, 2003 5:09:03 PM

In the short term it seems it would be expensive to keep tooling for Tbred A, B, and Barton, with Opteron and A64 on the horizon.

Long term it will be just Thorton (whatever the core turns out to be), Opteron and A64.

I don't know what to think.

I recently bought a t-bred b from SVC (JIUHB 0319) and put it on a new A7N8X with Kingston DDR PC3200 HyperX 1 GB Kit 2X512 RAM. Right away it went to a 200X11 at 1.5V (running stable about 32C.) Wouldn't post at 11.5 though. You think if I bump the voltage up it might help? I changed the Memory settings to Agressive and this shot up CPU performace according to SiSandra... Also, is this chip locked? I have heard somepeople say that T-Bred Bs are not locked and some say they are...

Hey guys.. I have been following this post for a while now due to the fact that I have just bought a 1700+ TBread (I think it is a "B" Im going to have to pull off the HS and check the codes again) with the intentions of OCing. I have a post titled What is going on? I don't know if you have had the chance to read it but if you could comment I would be grateful. 1700+ in a MSI KT3 Ultra mobo. My problem is that the bios will not let me pump the Vcore above 1.6. Is there anything I can do? I called MSI and they said that cpu is locking out the bios
from going over 1.6. All further I can get this unit right now is 11.5 X 146. Sorry to throw my problem into this thread but I wasn't getting any responce on my thread and you folks seem to have you hand on the pulse of the 1700+ COing. Thanks again.

I find that really hard to believe, but if it's true, damn! stock voltage 11*200, I have an A7N8X D 11*197 1.725v on a tbred b.

Oh well :(  I don't understand.

Bump up the voltage to 1.75 see how far the mult goes. You can go up to 1.85 if you want, no harm will be done, seriously.

You'll prolly get to 11.5, then u need to start incrementing the fsb 1 by 1.

Good luck, don't forget to put the VDimm up too.

August 28, 2003 12:59:06 PM

Thanks for the response. I found out the problem. The KT3 Ultra mobo will only allow me to bump up the Vcore .1v over stock per the CPU. I will have to use the pin connection trick to set the default Vcore up higher on the CPU. Take care all.

hat, I am a newbie at overclocking. A friend of mine told me to buy the processor from SVC because it was from a very good build week. He told me that I would have to get good ram CL2,2,2 ram to take full advantage... I don't know.

being new, I don't understand something. how do you increment the FSB 1 by 1? in the bios (on the A7N8X) i only see the options for 200, 166, etc... obviously it's possible if you are at 197. Can you explain the VDimm up too? If it is just setting the mem timings to aggressive,

also, what about the b-core. is it locked for higher multipliers? just trying to figure out my limitations before i try to push them.

rrfarle sorry for not answering earlier.

In the bios, (I can't remember off hand) but in the advanced chipset options you need to set I think the top most option( the one that does the fsb speed) to "user define" it lets you increase the fsb in 1 increments. I managed to get mine running stable at 200 and I'm now testing 202fsb. I can't believe I'm getting this high on a 1.04 version of the board!

Make sure you set the memory fsb to 100% a bit further down the bios screen. About the VDimm, well in the same way you need to increase VCore for a CPU the more you overclock it, you need to do it for the RAM too. I can't remember the name of the option but it's down near the bottom of that same screen we're talking about and and the values are either 2.6, 2.7 or 2.8. I have mine on 2.8 for 202 fsbs above about 190.

I'm not too sure what you mean by "b-core" and being locked for higher multipliers. The Vcore is not locked or attached to any multiplier. A little tip though, when you get past around 2100 - 2200 you'll need to increase the VCore much more to get little increases in speed.

Just added: It's the "system performance" setting, set it to "menu" and you can manually change everything else.
