We have a Surface Pro 2 that we've been using as a kitchen computer for 4 years (10" display, Core i5, 4 GB RAM, 64 GB SSD). It's dying.
Things we liked about it:
1) Cheap (purchased as open-box refurbished unit at Microcenter for ~$300 including Type Cover)
2) Versatile (can easily edit Word...
Indeed. It's a curiosity question with regard to threadripper and the relationship between package power and power allocated to the CPU cores themselves when operating at the default TDP limits.
The Anandtech review appears to show a potential performance issue caused by running at higher...
An inquiry for folks who have spent some time running their 1950X at stock speeds to satisfy my curiosity:
Background: When running the 1950X CPU at stock speeds but with RAM "overclocked" (e.g. running at 1.35V and DOCP speeds instead of "default" 1.2V JDEC speeds), there is a possibility of...
If you want someone to justify your purchase, here you go: If having the best possible gaming performance will make you a happier person and let you sleep better at night, and you can easily afford a new motherboard and CPU, go for it. Sell the current parts, reclaim 60-70% of the purchase...
123-125 watts at idle sounds high. These guys measured 48W at idle on their gaming desktop (with GTX 1080 no less) and 125W during "content creation" loads (i.e. CPU heavy, not GPU). I've seen similar 40-60W numbers [system idle at wall] in other Ryzen reviews. Maybe you have some power...
Indeed, that's what I've arrived at: Doubling the power usage yields only a 15-20% increase in clock speed. And you lose turboboost for single threaded tasks. And you lose all advanced power management. There also appears to be some legitimate binning happening, given how much voltage (and...
Two things in response:
1) At stock speeds, the Ryzen chips are binned to have an impressive amount of performance per watt -- if you have an application that can use 8 cores and 16 threads. But you definitely trade single-threaded performance compared to Intel's highest clocked chips.
2)...
Hi Folks,
One more try for the picture, which is a 1000 words, as the saying goes. Here is a link to Google Photos in case this doesn't work:
https://photos.app.goo.gl/hKZvGb1N9lQESzBy1
Things to consider:
1) Increasing the base clock to just 3.4 GHz on this 1700 resulted in a 109W increase...
Thanks folks! This is a helpful start!
The video posted by Reinvented is quite worrying. *See table below, which is a screenshot with my annotations*. This particular system is showing a 93W increase in power draw under load at just 3.2 GHz. Mind you, this is full system power at the wall...
Is there potential for an "eco-friendly", near-stock-voltage overclock of a Ryzen 1700 that won't cause a loss of single-threaded performance?
I'd like to maintain low idle power usage AND keep load power reasonable. What is "reasonable" to me? Generally no higher than the stock 1800X (about...
I just wanted to finish my story, in case someone else is in a similar situation with their Vaio Z.
I found a used LCD VGA cable on eBay for under $10 delivered, took the laptop apart, and installed the "new" cable. When I fired-up the laptop... The same black vertical line appeared in the...
Thanks. I know the displays are available, but I was hoping to get some greater insight into whether it is the display or the cable (not sold with the display) or another issue. I know it is gamble either way (my issue might be from a different cause), but I'm happy to learn from someone...
I tried to send a private message, rather than revive this VERY OLD thread, but apparently I don't have enough posts to send messages to the administrator group.
I'm curious to know if your father repaired his Vaio Z's screen (2010 era with 1080p display) and what the cause of the problem...
I am a huge fan of Microcenter. If they do custom configurations, I wasn't aware of it (and would never have looked for it, either, in the past).
If that is the case, and they let you purchase components directly from Microcenter (at their low prices) and just charge a build fee + warranty...
Hi Folks,
Thanks for the recommendations from folks who have personal experience and/or credible knowledge about particular vendors. Do any of these companies have online configuration tools aside from Puget systems?
Fujitsu does not appear to sell desktops in the US. And "sometimes I look...
Hi Folks,
Thanks for the replies so far, which unfortunately echo what I had feared. So, there are no major players that serve this market anymore?
It's painful to hit the "customize and buy" button on Dell's website and find out that almost nothing is customizeable outside of purchasing...
I'll be starting a new research job in the coming months. A new computer is part of the package. I'm not interested in the standard computer they typically offer (i.e. 15.6" laptop with 1366 x 768 resolution screen, spinning hard disk, and weighing in at 6-7 lbs).
What I want is a desktop...
Startech, it is possible that most modern SSDs would start performing GC duties before the drive got that dirty. Or that a couple of seconds of idle between writes would be enough time to do some maintenance. That's what I would hope for. Our only experience with SSDs in these systems are...
I came here for friendly advice, but I seem to be getting some attitude. I'm not sure why.
I won't go into the details of our funding, but suffice it to say that we do a lot of work on a relatively small budget. Important work, in my estimation. Please realize that it is rare to get full...
To Smoblikat: Yes, that would be great, but we have limited control over the software and hardware.
To Cerb and others: Yep, it's likely that I'll just have to test one of these drives over an extended period of time and see how it does. I personally gravitate towards the...
You may be right, though I'm not sure how I would implement this. We are dealing with proprietary software. They don't give out installation discs with these instruments. We clone our hard disks in case of failure, otherwise you have to wait for the company to send you a drive with the...
Thank you for the range of insightful comments.
To jwilliams4200: I did not mean to dismiss your drive recommendation or solid advice. I was still hoping someone would know of a non-enterprise SSD with garbage collection algorithms that would work well under these conditions. If getting...
Yes, this is exactly the case. We had small SSDs (30 GB), from an earlier generation, inside an instrument that's "only mission in life" was to fill them with small files. Files that would get 'deleted' to make space, but without TRIM or Garbage Collection. One disk failed. Both slowed down...
I appreciate the pitch that you are recommending to the 'boss', but this is academic research, so we aren't generating revenue. I was hoping someone would have an idea regarding which SSDs might work for our application. Basically, something that doesn't wait until idle, or until large write...
We can only realistically afford ~$200/drive, since we have several instruments. That rules out the Intel 710 series ($400 for 100GB model).
I see one vote for the Intel 320 series ($200 for 120GB). Any further insight into how garbage collection works on these drives?
Thanks for all of your replies (there are several now!). Throughput is actually very low - just a small ASCII file every few seconds, for a total ~100GB/yr (or 2 GB/ week). The instrument writes much less data than a laptop that hibernates once per day. The problem is that the writes are...
There is nothing wrong with the drive. As stated by ShintaiDK, smaller SSDs typically have much lower write speeds. The drive will be plenty fast under normal usage patterns, which involve a lot more reading than writing.
I've been keeping up with the world of SSDs via Anandtech reviews, but I have a question that requires some in-depth knowledge of controller behavior.
We have a half-dozen scientific instruments that record data every few seconds - accumulating about 100 GB of data per year (which we clear off...
I forgot your battery life question. Most 5400 RPM notebook drives are very power efficient. I can't imagine that your hard disk accounts for more than 15% of your battery usage, so even if the SSD used half as much power you'd only see a trivial gain in battery life. And from what I've...
You have to do a power analysis. I wish I could be more helpful, but my stats (particularly related to power analyses) are rusty, too! Check out the bottom of the page for an example.

Your situation is more complicated, however. You are...
A SSD is highly recommended if you want your system to feel more responsive. Two considerations, however:
1) How much storage space you can realistically live with? Unless you've got a big budget, you'll have to live with less space.
2) What are your workloads? A SSD will make...
FYI the Toshiba R705 is now down to $699 at Best Buy. That makes an already good deal even better. Though mind the cons from the Anandtech article, because it's only a good deal if you can live it
I don't know if this is too late, but I purchased the Toshiba R705 model from Best Buy a week ago. And yes, the screen is quite poor. When I put it next to my (fairly nice) desktop monitor, gosh, the laptop screen looks entirely washed out. Especially when displaying the same desktop image...
