Chargie's Journal

Hi guys and gals, I started to blog about my exercise, food intake and my thoughts along the way to burn fats and increase cardiovascular capacity.

Weight: 73kg
Height: 170cm
Fat % : 19%
Waist : 88.5cm

10 years ago,
Weight: 72kg
Height: 170cm
Fat % : 7.5%
Waist : 81.5cm

Its a big difference although the weight difference is by 1kg. I wish to slim down my body to less than 10% body fats and at the same time increase the cardio capacity over 4 months.

Please advice. Thanks!

Safe Vcore for Overclocking

charge-n-go — Fri, 25 Aug 2006 13:29:40 +0800

I know many ppl want to know what's the safe Vcore range. In fact, you have to download the manufacturer's specification sheet and look at their electrical datasheet.

There are a few important parameters:

Absolute rating
the voltage that might cause CPU to DIE INSTANTANEOUSLY.

Vcore_max_AC
the maximum voltage spike the CPU can handle. It only can happen in a short time.

Vcore_max_DC
the maximum core voltage that user can set in BIOS. For example, boosting from 1.40V to 1.50V.

Vcore_nom
The default Vcore

The attached image is the voltage waveform found in AMD Geode's specification sheet.
You can clearly see the relation between Vcore_max_AC, Vcore_max_DC and Vcore_nom

This thread is opened for us to discuss anything about AMD K8 stuff.

MODEL NUMBER
Server Processor - AMD Opteron
Extreme Processor - AMD Athlon64 FX
High End Desktop - AMD Athlon64 X2
Mid Range Desktop - AMD Athlon64
Budget Desktop - AMD Sempron
AMD CPU COMPARISON ---> Check most of the info here (Vcore, Watt, Process Tech......)

CPU-z 1.33 -- u can use this utility to check CPU stepping

// more info on K8 CPUs, will update later......

I'm not sure how many people aim for a stable overclocked system like me. Nvm, i'll js start this new thread and see how many ppl participates

Objective: This thread is created as a reference for forumers to know about some tested 'stable' settings. Well, it's kinda show off for your system stability too

Prime95 / SP2004 ranking

1. Ranking based on number of hours. Main aim is to test CPU, RAM, FSB stability in parallel.

2. Run 2 instances of Prime95 / SP2004. One for CPU and one for RAM/FSB stress test. Must be able to pass 12 hours of stress test. Less than that are not acceptable.

3. Screenshot must show "passed 12 hrs"together with CPU-z (1st tab) .

..................................................................................................................................................................

Full load strictly on Prime95 / SP2004:
I prefer prime95 24hrs bcoz it's really an indicator of stability. last time i was able to run 21 days UD (something like folding). Well, after 21st days my system auto restarted, so i tested with Prime95. Found out tat it failed during the 6th Hour !! After that detune the settings so that prime95 can run for 24 hours, and then able to run more than 1 month of UD without any laggy problem due to instability.

..................................................................................................................................................................

How to run 2x Prime95 in one shot?:

- copy and paste the prime95 folder.

- to run CPU stress test : option -> torture test -> custom.
Set min FFT to 8K, max FFT to yr L2 cache size. TICK 'run in place FFT' and set to 1 min.

- to run RAM stress test : option -> torture test -> custom.
Set min FFT to 8K, max FFT to 4096K. RAMsize = 1/10th of yr system RAM, UN-TICK 'run in place FFT' and set to 1 min.

..................................................................................................................................................................

For HT/ Dual Core system
"i think for computers with HT, dual core, or other PCs with "more than one CPU" should have prime95 running on separate affinities. if it's not changed, then at the end of the day, regardless of how many instances of prime95 is run, your CPU utilisation would be 50% at most." - thanx myuu for reminder

SOFTWARE DOWNLOAD
Prime 95 download
SP2004 download

..................................................................................................................................................................

Uptime ranking

1. Ranking based on the number of days your computer runs without restart.

2. System uptime must have at least 7 days continuous .

3. Full load uptime is more preferrable.

How to check uptime?

- show your LAN connection time.

- use Sisoftware Sandra. At information module, choose 'windows information' and check for 'time since start-up'

..................................................................................................................................................................

Please include this in your post, for example:

CODE

CPU : AMD Athlon64 FX-57 (3.30GHz @ 11x300MHz, 1.550V)
core : San Diego
socket : S939
RAM : 2x512MB OCZ TCCD (DDR600, 2.5-4-4-8, 2.90V)
M/B : DFI nF4 LanParty SLi-DR Expert (300HTT, 3xLDT, 1.70V)
PSU : Enermax Liberty 600W
Cooling : Thermalright XP-90C, and blablabla, u describe it;)

Computer Engineering Thread

charge-n-go — Wed, 12 Oct 2005 03:03:52 +0800

4 Simple Rules :

1. Post anything related engineering. It can be electronic stuff, gate level stuff or architectural discussion on any computer components.

2. If you don't know anything about engineering, please do not comment here, js read the posts by other members and try to understand them. Well, you can always ask questions if u don't understand

3. Questions related to engineering can be asked. No question such as "Is this processor good or not?". Of course you can ask :"Why this proc A is better than proc B?", but expect the answers are in term of engineering.

4. Bump this topic if it's going dead

Well, basically this is a thread for e&e engineering professionals, graduates and undergraduates to discuss some new technology.

Well, I'm not sure if my concept on HTT is correct. From what i know, not all the review sites gave the same concept about the HTT on Athlon64 system. Some said the HTT has something to do with memory and some said no. Even the DFI-street mentioned this : " Basically HTT is your memory controller's communication speed". However, I found out from AMD datasheet that HTT is not related to memory controller at all, as they are 2 independent units.

So I would really appreciate yr opinions and thoughts regarding HTT.

Some simple rules in discussion:

1. When you post any facts, state the source. (links or screenshots)
2. NO bashing or flaming.
3. You can make comparison of HTT with FSB.
4. No discussion that is not related to topic.
5. Pls stick to HTT on K8 system only.
6. Technical discussion is welcomed.
