I have been increasing the Multiplier this evening and got it running nice and stable at 14 x (instead of 11).  It has been slow progress as the benchmarks take a while to run, but I thought the data might be helpful.  Anyway, it is not exactly uncharted territory as FatBob got his JIUHB up to 14 x too, but I'll try 15 tomorrow (14.5 is reserved by AMD) and then start to look at the FSB.  Benchmark increases are set out below.  

The current increase in multiplier means that the 1.47GHz CPU is now running at 1.871GHz, a 27.2% increase and providing a PR rating of circa 2713  :D

A good first night's work on the CPU.  I'll get around to doing a little bit more tomorrow, but I guess that the most time will be spent on it on Monday.

Well a Multiplier of 15 works just fine and gives a PR rating of 2907.  It seems as though it system is very comfortable with the higher multipliers.  I may see how much higher they can go, but I suspect that I will start to look at raising the FSB now instead so as to increase the memory bandwidth.  At the stock 133MHz (133*2*8 = PC2100) the 434MHz (PC3500) OCZ RAM sitting in the mobo is somewhat underused as you can see from some of the results.

The 15x setting results in the 1.47GHz 1700+ CPU running at 2.005GHz with a PR rating of 2907.

I'm off out for most of the day now, but here are the benchmarks for the 15x tests.  Temperatures seem reasonably steady at 45-46 under load, i.e. all the benchmarks that get run one after the other!

I have to say I am quite pleased with the results so far from a £45 CPU  :lol:   I might not do much more tweaking today as I am out now until late afternoon, but if I do then I'll post the results up.  However tomorrow should be THE day for finishing the main FSB/Multiplier overclock, I'll then settle down to try to tweak the RAM settings etc to make sure they stay loose enough for the overclock.

TL, you will get better performance from raising the FSB to say 166Mhz.  Not sure what the multiplier will go up to at that speed tho!

When raising the FSB make sure the PCI and AGP busses are not being over clocked!!!  some motherboards determin their speed by a simple clock divider which means Mhzs over 133 is overclocking them... 166 is fine but take it to 170 and your again over clocking them by 4Mhz.

The AGP and PCI buses are locked and controlled separately on the NF7-S mobo - one of the reasons I chose it  :D   I just wanted to see how the set up responded to the multiplier changes first as I didn't have the time yesterday to do the FSB increases (they involve moving clock dividers & multipliers as well at the same time).  It has also given me some reference data to see how the system is performing compared to the multiplier changes.   I will be trying to up the FSB tomorrow when I have more time.  The RAM will cope with a 217MHz FSB, but I am not sure the rest of the system can and I don't want to take the system that high as it would probably go beyond the Vcore limits of the mobo, but we'll see tomorrow how high we can get - I am hoping to get it past 2.4GHz, but that may be wishful thinking - wish me luck  :wink:

Currently still playing with the 15x Multiplier.  The FSB is at 150 at the moment giving the cpu a 2.26GHz rating with a PR rating of 3271.  I just had to up the voltages a bit for this multiplier, but I am keen to see how high I can go with the FSB and still on a 15x multiplier.  If I top out too earlier then I'll drop down to 14x and lower, reset the voltages and start upping the FSB again.

More reports later and when I am finished I will put up the full table of data.

A quick update prior to the 6.00pm clan match match tonight.

The afternoon has been spent gradually reducing the multiplier and increasing the FSB to ensure the memory bandwidth was fully utilised.  The OCZ PC3500 is running successfully in synchronous dual channel mode the benchmarks for the bandwidth are scarily high!

Currently the system is running the FSB at 222MHz with a clock multiplier of 10.5.  This gives the cpu speed as 2.34GHz and an AMD pr rating of XP3393+  :D

Big shout out to FatBob as we spent the best part of an hour talking through settings on his and my PCs.  At the end of it all we managed to get both our machines to run in excess of 3300 and I believe that there is a bit more to squeeze out of the system itself.

Once the system is sorted, then I will tweak the RAM settings and start overclocking on the graphics card.  Currently the gfx card scores 14515 in 3D2001SE.

what are your reported temperatures tealeaf?  and if you have a thermonitor give room temps too :-)

I have no idea what room temperature is here, but it has had a window open all day because it has been warm enough to do it!  I guess 19-20, but I'll try to dig out a thermometer for a more accurate reading.  The CPU itself is running at about 47-48 centigrade, which is well within sensible tolerances.

I'll post some more info up later tonight, I am still trying to tweak those settings upwards  :D   Not bad though for a £45 CPU, eh?

OK, so here is the latest:  With Vcore 1.65v, Vchipset 1.7v and Vram 2.8v I got the FSB to 225MHz, however at that speed the system bails out of 3DMark2001.  As I do not want to up the voltage any more at the moment I have backed off to 222MHz FSB and will keep this (for the timebeing) as my standard FSB speed.  I am running a clock multiplier of 10.5, so the £45 JIUHB 1.43GHz XP1700+ is running at:

Current Speed: 2.338GHz  equivalent to an XP 3392+  :D  

System temperature at that speed is 30 and the CPU temp is 49 under prolonged load.  Remember, this is ALL with stock air cooling, nothing fancy, just fans and air.  When the system has run for a week or two, I will probably look at upping the voltage a bit more as the Abit NF7-S tends to undervolt, so running e.g. 2.8v Vram actually means about 2.7v.  This should allow a little bit extra on the FSB.  

The OCZ PC3500 Dual Channel RAM is performing prodigiously.  It is coping very well at 444MHz and could go another 30-36MHz higher if I can get the FSB increased. However at its current speed it is providing an absolutely massive amount of bandwidth - 3424 Mbps (SiSoft Sandra Integer Buff test) and 3206 Mbps (under the Floating Point Test).  The benefits of running synchronous dual channel ram rather than a single stick of ram are extremely clear - this single point was the biggest difference between FatBob's and my system.  

The benchmarks are set out below.  The first number is the original baseline benchmark prior to any modification, the second bold number is the new overclocked result.

SiSoft Sandra Pro
CPU Arithmetic Benchmark - 7669 >>> 12253
CPU Multimedia Benchmark - 16732 >>> 26505
Memory Bandwidth Benchmark - 3908 >>> 6630

3DMark2001SE
3DMark2001SE Score - 11442 >>> 15070

PCMark2002
CPU Score - 4501 >>> 7219
Memory Score - 4060 >>> 6273
HDD Score - 1139 >>> 1167

3DMark2003
3DMark2003 Score - 3962 >>> 4287

As yet, the Sapphire 9700 graphics card is running at totally stock speeds.  I will try to have a look at overclocking it during the week as I think that should add a fair amount to the graphics based benchmarks.

Anyway, the majority of the 'system' overclocking has now been done - I hope you have enjoyed reading about it as much as I have enjoyed tweaking the system.   I will post more here as and when I get round to getting the number any higher.   :D   In the mean time, why not go out and get one of those cheap as chips chips  :roll:  and go and overclock it yourself, eh?  But please make sure you post your benchmark results so that we can all enjoy the efforts of your hard work.

The system will be coming to the LAN, but for the moment, I believe my work here is done  :smokin:

Excellent stuff TeaLeaf, that was a pleasure to read. What was the total cost of the system?
Cheers, Bert

The cost depends on what you are re-using from your existing system.  My decision was made easier by the need to separate my business and leisure activities and and a big expenses claim being paid  :D

If you re-use your case and peripherals then the upgrade would cost £275:
Athlon XP1700+ (JIUHB) - £45
Abit NF7-S Rev 2.0 - £90
OCZ Twin 2 x 256MB PC3500 Dual Channel DDR RAM - £140

I also added a new cooler, aluminium case and some high quality peripherals:  
Aerocool DP-101 Deep Impact CPU cooler - £51
Sapphire Radeon 9700 128Mb - £185
Enermax 550W EG651P-VE FMA Blue - £105
Western Digital 120GB Special Edition 8MB cache HDD - £116
Lian Li PC-65 with window - £105
Arctic Silver III - £5
Silver Floppy - £11
System Total: = £853

I still think that this represents absolutely storming value whenyou think that a comparable retail CPU running at a slower stock speed would cost you about £450 on its own!

The Tweakmonster BGA RAM heatsinks for the 9700 graphics card arrived this morning so later today I will try to lap the bottom surfaces before mounting them.  I'll post some pictures and details of how and with what etc when I have got the job done.  I am also aiming to install the Lian Li temperature guage today now that the round silver Akasa cables have arrived.  Again, I'll post some pictures up when this has been done.  

When it is all put together I will try to up the graphics card speed using a straightforward overclock of the gpu and ram frequencies (with the aid of the extra cooling provided by the bga ram heatsinks) and flashing a new graphics card bios (warp11 and mufu variants).  I will post benchmarks for before and after as usual.

TeaLeaf,

A good set of forums that I use for nForce2 based boards is nForcers HQ ( http://www.nforcershq.com/forum/ ).

I've found some really useful stuff on there regarding minor niggles I've had with my A7N8X Deluxe, and the ABit forum is pretty active too.

The chaps on there might be able to help you wring that last bit of performance out of your new beast.  Although, to be honest, it sounds like you've a pretty good handle on things already  :D

Anyways, just an FYI...
